Allow base64-service-account-json key auth Issue: #923

[rbaker1]

resolves #923

Problem

Currently, JSON key files can only be represented as a string. There is interest in being able to set the GCP service account as a base64 encoded string.

Solution

The user can input either a base54 represented JSON key file or a normal string. There is testing involved to ensure it is invoked correctly.

Thanks for this @rbaker1! The change looks straightforward, especially with the tests you've added. I left one nit about method naming. Otherwise, this lgtm; I'd like an engineer from the team to review before we merge this in. I also added the user docs label because we'll need to open an issue for updating these docs on BQ connections.

It's my pleasure - should I make the doc update issue or will another member?
