ipaplatform: Drop the base authconfig class

As authconfig is a distro-specific tool there is no incentive for
implying that other platforms should implement any authconfig
implementation of their own.

-    IPA *expects* names of AuthConfig's options to follow authconfig(8)

-
-    Actual implementation should be done in ipapython/platform/<platform>.py
-    by inheriting from platform.AuthConfig and redefining build_args()
-    and execute() methods.

-    ....
-
-    See ipapython/platform/redhat.py for a sample implementation that uses
-    authconfig(8) as its backend.
-
-    From IPA code perspective, the authentication configuration should be
-    done with use of ipapython.services.authconfig:
-
-    from ipapython import services as ipaservices
-    auth_config = ipaservices.authconfig()
-    auth_config.disable("ldap")

-    auth_config.add_option("update")
-    auth_config.enable("nis")
-    auth_config.add_parameter("nisdomain","foobar")
-    auth_config.execute()
-
-    If you need to re-use existing AuthConfig instance for multiple runs,
-    make sure to call 'AuthConfig.reset()' between the runs.
