Description

Fixes #b/394374465

Intending to use this snippet on the following page:
http://cloud/media-cdn/docs/quickstart#terraform

Leveraging the quick start documentation so new declarative features (compression_mode, allowed_methods, url_rewrite) may have a Terraform example.

Checklist

Readiness

• Yes, merge this PR after it is approved
• No, don't merge this PR after it is approved -- we need to coordinate with the team for the public launch

Style

• My sample follows the rules described for Terraform in the Effective Samples style guide
• My sample follows the other requirements and best practices in the Contributing
  guide

-ish -- this is the only place in Media CDN that resources are "created". There are other places where resources are modified, i.e. a new option (created by a new feature) is turned on/off, or set up with required options.

Testing

• I have performed tests described in the Contributing guide:

Yes, but I was not able to use the test infrastructure because I did not have the createProject permission. So I tested the changes in my own project. Notes here:
https://b.corp.google.com/issues/394374465#comment11

• Tests pass: terraform apply
• Lint pass: terraform fmt check

Intended location

• Yes, this sample will be (or already is) included on cloud.google.com
  Location(s): http://cloud/media-cdn/docs/quickstart#terraform

Note, no further updates need to be made in that page, because we are just updating the sample, not creating a new one.

• No, this sample won't be included on cloud.google.com
  Reason:

API enablement

• [N/A] If the sample needs an API enabled to pass testing, I have added the service to the Test setup file

Review

• [N/A] If this sample adds a new directory, I have added codeowners to the CODEOWNERS file
