Add change log count to user response payload

[mitchell852]

I'm submitting a ...

• new feature / enhancement request

Traffic Control components affected ...

• Traffic Ops
• Traffic Portal

Current behavior:

I don't believe there is a way currently via TP and/or the TO API to see how many change log entries have been created by a particular user. IMO this information would be helpful when evaluating user activity along with #5412

New behavior:

Do one of 2 things or maybe both:

1. Add changeLogCount to the response payload of the user TO api endpoints (this would require a join to the log table)
2. add query param support such as GET /logs?username=

Anything else:

If this is added to the api, then it needs to be added to TP as well. I.e.

• https://tp.domain.tld/#!/users should show the changeLogCount in the grid
• https://tp.domain.tld/#!/users/{{id}} should have a new button called 'view change logs' or something.

Per API spec guidelines if you did GET /logs?user=someone&limit=0 then you could get back

{
	"response": [],
	"summary": {
		"count": 50
	}
}

assuming someone had 50 associated changelog entries. If we implement summary on that endpoint, that is.

what i meant was something like this for GET /users

    "response": [
      {
        "username": "my-username",
        "email": "email@email.com",
        ...
        "changeLogCount": 50,
      }
    ],

in addition to providing the user query param to the logs endpoint: GET /logs?user=someone

I can take this one.
