The OAuth2Client library has been deprecated by Google since 2018, and there is a replacement library google-auth.

Description

If a provisioner cannot be accessed, e.g. OAuth server is down, allow step-ca to boot up with the remaining functioning provisioners. Probably this is already in the new management revamp but it's worth keeping an issue for this. @dopey could you confirm this?

Use case

This is part of my recent hiccups when bootstrapping a fully integrated server after a long power outag

If you create a custom ICertificateAuthorityConfiguration and pass it to say a step-ca authority, with a custom port in the URL the FileSystemAccountStore tries to put the port in the directory name and fails.

Can we change from AuthorityUri to Host?

As @rjkroege mentioned in rjkroege/edwood#288 tokenizing the results of the getarg function would allow for more robust parsing of the given arguments.
