Add new terraform sample - CDN XLB with Backend Bucket

[msampathkumar]

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.

I have triggered VCR tests in RECORDING mode for the following tests that failed during VCR: TestAccDataprocMetastoreServiceDatasource_basic|TestAccComputeGlobalForwardingRule_externalCdnLbWithBackendBucketExample|TestAccContainerCluster_withAuthenticatorGroupsConfig|TestAccFirebaserulesRelease_BasicRelease|TestAccServiceNetworkingPeeredDNSDomain_basic|TestAccSpannerDatabase_postgres You can view the result here: https://ci-oss.hashicorp.engineering/viewQueued.html?itemId=274382

Whats the reason for adding this example? I'm worried because it's a fairly large example with a lot of config and it will be added to our docs page here: https://github.com/modular-magician/terraform-provider-google-beta/compare/auto-pr-5869-old..auto-pr-5869#diff-0bd72faa5634a22f080fa06fe8346998911d494e1f50499d29d1bb67586aaa7eR40

Can we restrict this to only the cloud docs if that is the intended target?

Hi @slevenick Thank you for your comment.

This code sample was requested earlier and merged - Github PR Request, but was later missing in the Master Branch.

This sample code is requested for users, as a demonstration. For more information, refer to http://b/227467966.

Most of the Terraform Load balancers samples are usually big as this one and I guess we did not restrict them. For this code sample, if it's too much trouble, I see it okay restrict to the Docs.

Looks like TestAccComputeGlobalForwardingRule_externalCdnLbWithBackendBucketExample is constantly failing in VCR and also failed in CI last night https://ci-oss.hashicorp.engineering/buildConfiguration/GoogleCloudBeta_ProviderGoogleCloudBetaGoogleProject/278011?buildTab=tests&status=failed&name=TestAccComputeGlobalForwardingRule_externalCdnLbWithBackendBucketExample&pager.currentPage=1&expandedTest=-5379752785185941961

[slevenick]

Huh, then why did it pass in VCR?

I guess I'll revert again!

[shuyama1]

I think VCR got timeout and did not run this test https://ci-oss.hashicorp.engineering/buildConfiguration/GoogleCloudBeta_ProviderGoogleCloudBetaMmUpstreamVcr/274382?buildTab=tests&status=all&pager.currentPage=1

If a beta-only test does not have provider = google-beta on the resources, it will fail in our nightly test but pass in VCR (#5852). I will look into the problem and try to get it fixed next week.
While this PR is more than that I guess. It seems lack of provider = google-beta on some resources but after adding it I still got errors
