Problem when using authentication with "service_account_contents"

##### SUMMARY
When i use authentication with "service_account_contents", many importants fields came with "*********", like 'selfLink' in gcp_compute_network_info module response. This is a problem because the network 'selfLink', for example, will go to use like input in gcp_compute_instance, and with "********" in response is there error. This field is not a confidential information, and can to be show.

Start with the google.cloud.gcp_compute_network_info module and the authentication path used by service_account_contents. Reproduce the response and trace where fields such as selfLink become masked; done means non-confidential fields remain usable as inputs while confidential values stay protected, with regression coverage for the behavior.
