Consider different modes of authentication for azure. #112
Description
Users currently have to explicitly specify service principal credentials to auth.
If we switch to accepting an access token, the CLI can automatically pull credentials from az login (with the azure sdk).
This problem doesn't exist in AWS, as AWS stores everything in plaintext in ~/.aws/credentials
The problem with this approach is it may be slightly more involved when going through the frontend. A user would likely have to go to the azure cloudshell and retrieve a token from there.
There are also issues with token expiration, but I think it may be possible to do something with refresh tokens.
