Move to 2020.1

Make changes to update_schemas.py needed for the move and run
update_schemas.py.

Need 1.3.6 or later version of Redfish-Service-Validator.
CI uses the master branch of Redfish-Service-Validator, which has
this fix.

Redfish-Service-Validators before 1.3.6 will incorrectly throw errors in
message registries like (Task Event Message Registry)
/redfish/v1/Registries/TaskEvent/TaskEvent and (Base Message Registry)
/redfish/v1/Registries/Base/Base.

For more information:
https://redfishforum.com/thread/323/validator-errors-when-moving-release

This does introduce some "warnDeprecated" due to "Severity" becoming
Deprecated in MessageRegistry v1_4_0. Since all bmcweb Registries are
<v1_4_0, not a real problem. Redfish has no Base Message Registry and
Task Event Message Registry available to move to something that
uses MessageRegistry v1_4_0. Will take up with Redfish.

2020.1 includes new features like AutoRebot (Boot -> AutomaticRetry),
factory reset (ResetToDefaults action), and Modified Event Log property
which are in OpenBMC's D-Bus interfaces today.

Tested: Built bmcweb, loaded on a Witherspoon, and ran
        the validator. Validator passed.

See new schemas:
curl -k https://${bmc}/redfish/v1/JsonSchemas/SecureBootDatabase
{
    "@odata.context": "/redfish/v1/$metadata#JsonSchemaFile.JsonSchemaFile",
    "@odata.id": "/redfish/v1/JsonSchemas/SecureBootDatabase",
    "@odata.type": "#JsonSchemaFile.v1_0_2.JsonSchemaFile",
    "Name": "SecureBootDatabase Schema File",
