Auth methods configuration

Added Oem extension for AccountService allowing user to configure
which authentication methods should be enabled. User is now able
to turn on and off authentication methods like BasicAuth, XToken, etc.
User is not allowed to turn off all of the methods at once - at least
one method has to be active to prevent lock-out. This configuration
is persistent, will be saved on file-system and will be loaded on
bmcweb's restart.

Tested:
No regression found in manual testing. By default everything works as before,
and disabling auth method prevents user to authenticate by it. Tested that
user is not allowed to disable all the methods - either in one PATCH or by
disabling them one at a time.
ServiceValidator run with success.
