task(auth): Expose more detailed session status info

[dschom]

Because

@dschom Looks like this endpoint was added 11 years ago f7783b3. This was well before there were many different verification states on sessions. It is possible that the original /session/status endpoint does not provide any value over the new endpoint your proposing.

Maybe it makes sense to combine them?

Does it make sense to combine this into the the /session/status endpoint?

There is also account profile route that exposes some of this information

[dschom]

It might. I was certainly considering this.

Initially I was concerned that this endpoint now also hits the account table as well as the session table, so it's quite a bit heavier than the /session/status call. I just checked our stats though, and it seems like this endpoint isn't heavily called. Account profile seems like overkill for what I plan to use this for since it's also pulling capabilities.

Let me know what you think. If you think updating /session/status won't break things I'll do that. I was also a little uncertain about who all called /session/status. Seems like it could be a pretty useful endpoint for RPs in general, and I don't know if they respond well to a change in response format.

@vbudhram I have updated this to just add on to the response of the/session/status endpoint. It seems like a couple integration tests are failing now, so just need circle back on that.
