saving role name to the Secret Internal data. Default revoke query added

The rolename is now saved to the secret internal data for fetching
later during the user revocation process. No longer deriving the role
name from request path

Added support for default revoke SQL statements that will provide the
same functionality as before. If not revoke SQL statements are provided
the default statements are used.

Cleaned up personal ignores from the .gitignore file
