Add Connection Aggregate

[nanderstabel]

Description

Add Connection Aggregate to UniCore.

This new aggregate needs to be added to the upcoming agent_identity domain and serves as a container for the agent's connections/entities with whom it has/will interact.

The aggregate needs to contain at least:

• it's own ID
• optional domain of the connection
• optional DID of the connection
• TBD

POST, GET and DELETE methods endpoints need to be added to a new /v0/identity/connections endpoint in agent_api_rest

The connection_id needs to be added to other aggregates:

• Offer (both issuance and holder)
• Credential (both issuance and holder)
• possibly more

Motivation

This will enable management of the relationships and interactions between UniCore and other entities.
