Commit Message

Stefan Schantl Dec. 2, 2020, 7:43 p.m. UTC
This option can be used to get a list of all known provider which support
a token based authentication method.

In order to provide this feature the provider details has been extended
to contain the information if a provider supports this authentication
method or not.
