Authorize with google cloud sdk application default credentials about google-cloud-rs

[GlenDC]

@Hirevo is this library still being supported? Do you need help?
I would also very much like this logic as for now I am having to polyfill it myself.
And while I do not mind putting in the work (as I will be forced to anyway),
it does seem like a waste of time that all of us need to implement this ourselves.

As such, can the PR of @plippe be looked at please? If not, can you tell us why,
so that he, I or someone else can take a second look at it, either by picking up the PR,
or going for a by you approved different approach.

Either way, as it stands now, the library is auth-wise very much under-supported,
which is a shame, as all the rest does seem to be pretty neat as-is. For which,
a big thanks!

Hey,

I am looking for something similar.

I have an application running as a Docker container on Google Cloud Run. I want to interact with Datastore, but I can't seem to obtain the service account.

As others have suggested, it might be worth rewriting the client creation to follow Google's default credential flow and avoid duplication.

I don't mind trying to write a PR. It shouldn't be too hard as the logic already exist in all the official libraries. I should have something in a week or two.

Would anyone have any advice before I start?

There doesn't seem to be much interest for my PR.
Therefore, I won't waste any time on it.
