Fix/endpoint attrib structure

[cjhowland]

This PR implements the solution discussed in #1928 to resolve an issue with the endpoint attrib structure. We have brought the structure into alignment with the did:sov specification by removing the nested endpoint structure and ensuring that service types profile and linked_domains can be used. This solution is interoperable with AFJ, which also supports endpoint attrib data in the following manner:

{
  "endpoint": "https://example.com",
  "types": ["did-communication", ...],
  "routingKeys": [...],
  "profile": "https://example.com/profile",
  "linked_domains": "https://example.com/linked-domains",
}

Looks like an integration test is failing -- could you please take a look. We have had some intermittent ones, but I think (hope) the last of those were recently fixed.

We're getting a failure on circleci that I haven't seen before:

Either git or ssh (required by git to clone through SSH) is not installed in the image. Falling back to CircleCI's native git client but the behavior may be different from official git. If this is an issue, please use an image that has official git and ssh installed.
Cloning git repository

error cloning repository: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

I'll try triggering an update on the branch and hope that resolves it.

Well, shoot. That didn't do it. Are these possibly related to the issues we saw in #1933?
