Title: [google|compute] Enable passing the google_key_location as a String

Google::APIClient::KeyUtils.load_from_pkcs12 allows passing the contents
of the PKCS12 key as a String instead of the PKCS12 file location.

Allowing this option when Fog::Compute[:google] is initialized enables the
automation on those environments where you can not send a file.
