The Management gRPC API has too much business logic
happening while it has to be in the Account manager.
This also needs to make more requests to the store
through the account manager.
Replace Peer.Key as internal identifier with a randomly generated Peer.ID
in the Management service.
Every group now references peers by ID instead of a public key.
Every route now references peers by ID instead of a public key.
FileStore does store.json file migration on startup by generating Peer.ID and replacing
all Peer.Key identifier references .
