Make CI/CD Cloud Provider Test Conditional

What does this implement/fix?

The cloud provider CI/CD test fails when run from forks of this repo which do not have credentials (and presumably, their own accounts) set up for the providers used by the test. This situation generates spurious CI/CD pipeline failure messages.

This PR adds the ability for repo fork maintainers to skip the CI/CD Cloud Provider Test by setting a repo variable 'NO_PROVIDER_CREDENTIALS'. If that variable is not set by the repo maintainer (the default case), the test behavior will be unchanged from before this PR.

LGTM, thanks for the contribution @tylergraff. I left a suggestion for rewriting the description a bit to also include the ref. issue, to help future contributions.
