Many tests failed at the same time in this package.

• I will close this issue when there are no more failures in this package and
  there is at least one pass.
• No new issues will be filed for this package until this issue is closed.
• If there are already issues for individual test cases, I will close them when
  the corresponding test passes. You can close them earlier, if you prefer, and
  I won't reopen them while this issue is still open.

Here are the tests that failed:

• getApplicationDefault should cache the credential when using GCE
• getApplicationDefault should use GCE when well-known file and env const are not set
• getCredentials should get metadata from the server when running on GCE (googleauth googleauth: getCredentials should get metadata from the server when running on GCE failed #1264)
• should allow passing a scope to get a Compute client
• should get an access token
• should get request headers
• should authorize the request
• should make the request
• sign should hit the IAM endpoint if no projectId nor private_key is available
• should return a Compute client for getIdTokenClient
