Support Service Account for Translation?

[omaray]

It seems like Service Account should be supported with the Translation API. For instance in Python: googleapis/google-cloud-python#2731

@jonparrott : can you confirm?

[theacodes]

Yes, it should

Once Service Account support is working, should API key support be removed?

[blowmage]

Looks like the python lib has removed API key support.

I looked at the implementation again, and it turns out we have already implemented support for service accounts last November. (issue: #1046, pr: #1050)

@omaray @jonparrott Currently we support both service accounts and API keys. Python has removed support for API keys. Should we do the same? Or should we maintain both modes of authentication?

[omaray]

Per the conversation with the API team, we should keep both (and thanks for checking and confirming).
