Redfish: Add PATCH operation support for RemoteRoleMapping

Added PATCH operation support for RemoteRoleMapping property under
LDAP/ActiveDirectory property in AccountService schema.

1. How to add the Role Mapping?

PATCH {"ActiveDirectory":{"RemoteRoleMapping": [{"RemoteGroup":
"Admingroup15","LocalRole": "User"},{"RemoteGroup": "Admingroup13",
"LocalRole": "Administrator"},{"RemoteGroup": "Admingroup14",
"LocalRole": "Operator"}]}}

With the above PATCH request, all the above role mapping gets added.

2. How to delete a specific role mapping?

After adding the above roles mapping, if user want to delete the second mapping
which is ({"RemoteGroup": "Admingroup13", "LocalRole": "Administrator"})

Following PATCH request would be used.
   PATCH {"ActiveDirectory":{"RemoteRoleMapping": [{},null,{}]}}

3. How to update specific role mapping ?

Let's take a case where user want to update the second role mapping
   PATCH {"ActiveDirectory":{"RemoteRoleMapping": [{},{"RemoteGroup":"Admingroup25","LocalRole": "User"},{}]}}
   or
   PATCH {"ActiveDirectory":{"RemoteRoleMapping": [{},{"RemoteGroup":"Admingroup25"},{}]}}  and \
   PATCH {"ActiveDirectory":{"RemoteRoleMapping": [{},{"LocalRole": "User"},{}]}}
Tested:

1. Did a PATCH operation with below given Data:

  ' {"ActiveDirectory":{"RemoteRoleMapping": [{"RemoteGroup": "Admingroup215","LocalRole": "User"}, \
   {"RemoteGroup": "Admingroup213","LocalRole":"Administrator"},{"RemoteGroup":"Admingroup214","LocalRole":"Operator"}]}}'

2. With GET got below given data:

 "RemoteRoleMapping": [
      {
        "LocalRole": "Operator",
        "RemoteGroup": "Admingroup214"
      },
      {
        "LocalRole": "Administrator",
        "RemoteGroup": "Admingroup213"
      },
      {
        "LocalRole": "User",
        "RemoteGroup": "Admingroup215"
      }
    ],

      },

      }
    ],

13. Did a PATCH operation with below given Data:

'{"ActiveDirectory":{"RemoteRoleMapping": [{},{"RemoteGroup": "Admingroup26","LocalRole": "User"},{}]}}'

14.With GET got below given data:

 "RemoteRoleMapping": [
      {
        "LocalRole": "User",
        "RemoteGroup": "Admingroup25"
      },
      {
        "LocalRole": "User",
        "RemoteGroup": "Admingroup26"
      },
      {
        "LocalRole": "User",
        "RemoteGroup": "Admingroup215"
      }
    ],

15. Try to delete the role map when there was no role map entry and get the following error.
  "RemoteRoleMapping/1@Message.ExtendedInfo": [
    {
      "@odata.type": "/redfish/v1/$metadata#Message.v1_0_0.Message",
      "Message": "The value null for the property RemoteRoleMapping/0 is of a different type than the property can accept.",
      "MessageArgs": [
        "null",
        "RemoteRoleMapping/0"
      ],
      "MessageId": "Base.1.4.0.PropertyValueTypeError",
      "Resolution": "Correct the value for the property in the request body and resubmit the request if the operation failed.",
      "Severity": "Warning"
    }

OpenBMC webserver

This component attempts to be a "do everything" embedded webserver for openbmc.

Capabilities

At this time, the webserver implements a few interfaces:

Authentication middleware that supports cookie and token based authentication, as well as CSRF prevention backed by linux PAM authentication credentials.
An (incomplete) attempt at replicating phosphor-dbus-rest interfaces in C++. Right now, a few of the endpoint definitions work as expected, but there is still a lot of work to be done. The portions of the interface that are functional are designed to work correctly for phosphor-webui, but may not yet be complete.
Replication of the rest-dbus backend interfaces to allow bmc debug to logged in users.
An initial attempt at a read-only redfish interface. Currently the redfish interface targets ServiceRoot, SessionService, AccountService, Roles, and ManagersService. Some functionality here has been shimmed to make development possible. For example, there exists only a single user role.
SSL key generation at runtime. See the configuration section for details.
Static file hosting. Currently, static files are hosted from the fixed location at /usr/share/www. This is intended to allow loose coupling with yocto projects, and allow overriding static files at build time.
Dbus-monitor over websocket. A generic endpoint that allows UIs to open a websocket and register for notification of events to avoid polling in single page applications. (this interface may be modified in the future due to security concerns.

Configuration

BMCWeb is configured by setting -D flags that correspond to options in bmcweb/CMakeLists.txt and then compiling. For example, cmake -DBMCWEB_ENABLE_KVM=NO ... followed by make. The option names become C++ preprocessor symbols that control which code is compiled into the program.

When BMCWeb starts running, it reads persistent configuration data (such as UUID and session data) from a local file. If this is not usable, it generates a new configuration.

When BMCWeb SSL support is enabled and a usable certificate is not found, it will generate a self-sign a certificate before launching the server. The keys are generated by the prime256v1 algorithm. The certificate

is issued by C=US, O=OpenBMC, CN=testhost,
is valid for 10 years,
has a random serial number, and
is signed using the SHA-256 algorithm.

Crow patches

The crow project has had a number of additions to make it more useful for use in the OpenBmc Project. A non-exhaustive list is below. At the time of this writing, the crow project is not accepting patches, so for the time being crow will simply be checked in as is.

Applied clang-format to the whole crow tree. This was done without regard for arrays and fixed data structures, but was deemed to be overall better than the inconsistent formatting that existed in upstream previously.
Crow server now calls stop before destruction of the Crow app object.
Fixed a bug where timed out websockets would seg fault the system by accessing a destroyed socket object without null checks when in SSL mode.
Added a TestSocketAdapter class that could be used to unit test server behavior without utilizing a socket.
Added the "getRoutes" call to both the app and the routing Trie class that allows consumers to poll the server for all (or a subset of) registered web routes in the system.
Hardcoded the websocket implementation for binary mode, instead of leaving protocol unspecified.
Move most uses of std::unordered_map to boost::flat_map to lower memory consumption, and (in some cases) to improve memory locality.
Adjust the addHeaders mechanism to use a fixed string instead of a full map implementation to avoid unnecessary mallocs and reduce the number of scatter gather buffers on an http response.
Change server name header from Crow/0.1 to iBMC
Starts the http server io_context inside the main thread, instead of creating a new thread.
Removes all BMCWEB_MSVC_WORKAROUND flags.
Removes the behavior that causes a 301 redirect for paths that end in "/", and simply returns the endpoint requested. This was done for redfish compatibility.
Removes the built in crow/json.hpp package and adds nlohmann json package as the first class json package for crow.
Move uses of boost::array to std::array where possible.
Add the ability to get a reference to the crow::Request object on websocket connection to allow checking header values.
Patch http handler to call middlewares on websocket connections to allow authentication to be applied appropriately.
Adds an is_secure flag to provide information about whether or not the payload was delivered over ssl.
