gcloud-aio-* (and probably also gcloud-rest-*) trigger gcloud hook, which fails because gcloud is not installed.

[burnpanck]

Describe the bug

When attempting to build a project which depends on one of the above mentioned packages, the gcloud hook is triggered because those packages install into gcloud.aio namespace package. However, the hook fails at copy_metadata("gcloud") with the error importlib.metadata.PackageNotFoundError: No package metadata was found for gcloud.

Indeed. The hook was written for this gcloud, hence the conflict. While both gcloud and pyrebase (from pyinstaller/pyinstaller#5316, which was original motivation for #68) seem to not be actively developed anymore, they are at least still installable and importable, so I think the best solution here is to wrap that copy_metadata call in try/except block and suppress the error.
