Add few additional properties in the LDAP config

User can provide these properties to configure the LDAP.

UsernameAttribute:
In certain ldap server userid is "cn" and in other ldap
server it becomes "uid"

GroupNameAttribute:
In certain ldap server groupid is gid and in other ldap
server is PrimaryGroupID etc.

Both properties exist in the LDAP server and admin of LDAP
server can opt for any property to specify the userID
and same is true for other properties(GroupName).

It is aligned with redfish also.
