[Story] Add capability management to Draupnir and MPS

[Gnuxie]

Description

As a protection developer, I should be able to describe the interface and dependencies needed by my protection to take actions in a room. Then provide an implementation for both "no operation" mode and the standard functionality. These implementations are called "capability providers".

As a draupnir moderator, I can see the active capability provider for each protection and read about the capability providers that they are compatible with. I should then be able to change the active capability provider for each protection as I see fit.

Acceptance Criteria

• When protections are listed in Draupnir, the names of their active capability providers are listed, along with the name of the capability interface.
• All of the compatible providers are listed when I look at the documentation for the protection
• There are commands to change the active capability provider for a protection.
• There is an API to define a capability provider and a capability interface.
• There are APIs to add a capability interface to protection and provide a suggested capability provider.

Total Pain

All of the internals that make this work are implemented fwiw, there's just no configuration or exposed UX. There's also no "dummy/blank" capabilities to use to plug interfaces safely.
