Method used to return the default GoogleCredentials and provide it as a bean. It will determine which credential in the following way:

1. If

   gcp.credentials.location

   is specified, use its location
2. Otherwise, if

   gcp.credentials.encodedKey

   is specified, decode it and use its content
3. None of the 2 properties were specified, use Application Default credential resolution. See Google Cloud Java authentication. This will resolve credential in the following order:
   1. The credentials file pointed to by the

      GOOGLE_APPLICATION_CREDENTIALS

      environment variable
   2. Credentials provided by the Google Cloud SDK

      gcloud auth application-default login

      command
   3. Google App Engine built-in credentials when running inside of Google App Engine
   4. Google Cloud Shell built-in credentials when running inside of Google Cloud Shell
   5. Google Compute Engine built-in credentials when running inside of Google Compute Engine or Kubernetes Engine

The GoogleCredentials
