Coexistence with PSRule.Rules.Azure

[BernieWhite]

Description of the issue

Currently the PSRule pipeline does not isolate module runspaces when called on the command line together.

For example:

Invoke-PSRule -Module 'PSRule.Rules.CAF', 'PSRule.Rules.Azure';

When internal functions use the same name they can clash and only one wins. In this case both module define a SupportsTags helper function.

Expected behaviour

Update helper function name with CAF_ prefix.

Module in use and version:

• Module: PSRule.Rules.CAF
• Version: 0.1.0-B2001009
