network_services: Dual-Token Authentication Support

[carlyeks]

Adds signed_token_options and add_signatures field to google_network_services_edge_cache_service and validation_shared_keys to google_network_services_edge_cache_keyset to support dual-token authentication.
Resolves hashicorp/terraform-provider-google#12775.

If this PR is for Terraform, I acknowledge that I have:

• Searched through the issue tracker for an open issue that this either resolves or contributes to, commented on it to claim it, and written "fixes {url}" or "part of {url}" in this PR description. If there were no relevant open issues, I opened one and commented that I would like to work on it (not necessary for very small changes).
• Generated Terraform, and ran make test and make lint to ensure it passes unit and linter tests.
• Ensured that all new fields I added that can be set by a user appear in at least one example (for generated resources) or third_party test (for handwritten resources or update tests).
• Ran relevant acceptance tests (If the acceptance tests do not yet pass or you are unable to run them, please let your reviewer know).
• Read the Release Notes Guide before writing my release note below.

Your assigned reviewer will help review your code by:

• Ensuring it's backwards compatible, covers common error cases, etc.
• Summarizing the change into a user-facing changelog note.
• Passes tests, either our "VCR" suite, a set of presubmit tests, or with manual test runs.

You can help make sure that review is quick by running local tests and ensuring they're passing in between each push you make to your PR's branch. Also, try to leave a comment with each push you make, as pushes generally don't generate emails.

If your reviewer doesn't get back to you within a week after your most recent change, please feel free to leave a comment on the issue asking them to take a look! In the absence of a dedicated review dashboard most maintainers manage their pending reviews through email, and those will sometimes get lost in their inbox.

@shuyama1 Can you take a look at this PR? I believe the test failure is transient.

[shuyama1]

@carlyeks Are you able to get the test passed locally?

[carlyeks]

Yes, I was able to get this test to pass locally:

[shuyama1]

LGTM overall! Do you happen to know if any of the added fields are immutable that can't be updated after creation?

[carlyeks]

No; these are all mutable fields.

[carlyeks]

@shuyama1: could you take another look at this?

[shuyama1]

Thanks!
