Initializes OAuth2 credentials.

This can use 3 different mechanisms for obtaining a credential:

1. It can fetch the application default credentials.
2. The user can specify a client secrets file and go through the OAuth2 webflow. The credential will then be cached in the user's home directory for reuse. Provide the property "secrets_file" to use this mechanism.
3. The user can specify a file containing a service account. Provide the properties "service_account_keyfile" and "service_account_name" to use this mechanism.

The default mechanism is to use the application default credentials. The other options can be used by providing the corresponding properties.

Throws:

IOException

GeneralSecurityException
