Context and scope

Applying the maester in my Ory network I noticed that error handlers are not currently supported.
This blocked me to implement oathkeeper-maester.

The design

By design, oathkeeper provides support to error handlers, which are responsible for executing logic after, for example, authentication or authorization failed.

The error handlers definition will follow the same structure of other handlers (authenticators, authorizers and mutators).
