MXS-862: Add create/destroy and remove plugin_name entry points

Browse Source 
The create and destroy entry points allow authenticators to store data in
the DCB. This data is not shared by other DCBs related to the same
session.

The plugin_name entry point wasn't really useful as the plugins would
still need to send a AuthSwitchRequest packet if they wanted to change the
authentication mechanism.
