[proposal] Align IDIDManager interface with DID Registration spec

^{Originally posted by **peacekeeper** July 7, 2022}
Hello,

At DIF we've been working on a specification called "DID Registration", which defines inputs and outputs of the DID create/update/deactivate operations, see here:
https://identity.foundation/did-registration/

Just like DID Resolution, these are abstract functions which can be implemented in various ways, e.g. as a local SDK, remote HTTP service, etc. There is also the Universal Registrar implementation of this at DIF: https://github.com/decentralized-identity/universal-registrar

The DID Registration specification seems to have some overlap with Veramo's [IDIDManager](https://veramo.io/docs/api/core.ididmanager/) interface. Perhaps it would be useful to align your interface with the specification, or conversely, incorporate ideas from your interface into the specification.
