fix(connection): set token expiration date for GCE
Browse files Browse the repository at this point in the history
A response from the GCE metadata server responds with data in a
different format from that of the GAPIToken() request. Instead of
looking for a property that doesn't exist `token_expires`, we now
calculate the expiration timestamp from `expires_in`.
