DID management component discussion

[goncalo-frade-iohk]

The reason for this discussion is there is a need for a better did management component. As part of this discussion the following is purposed:

• Separate Plutos DID Management side into a more flexible protocol.
• Make the DID management data more common, aka: instead of having a different storage for PrismDID and PeerDID have a storage for DIDs.
• Make a DID Management default component that is capable of manage (search, create, update, delete) DIDs and is components in the database.

Then make this component available within PrismAgent.
