This pull request updates the getRegionalAccessBoundaryUrl method in the Compute client to validate the format of the service account email, returning null if it is invalid or missing. It also adds comprehensive unit tests to verify this behavior. The feedback suggests moving the regular expression definition to a module-level constant to avoid recreating it on every function call, which improves performance.

In computeclient.ts, the resolveServiceAccountEmail function could return a non-email.
In such cases, we skip RAB lookup, log the skip once for user and avoid making any future MDS calls.
Added tests for this.
