Factor up config dependent credential classes

Separate helpers methods to build credentials, credential providers and
client managers that depend on configuration. They are all moved to
the common.credentials module to achieve two objectives:
- prepare credential provider module to move to tempest-lib
- avoid circular dependencies

There are still dependencies to CONF in the credential providers,
removing all of them would make the patch too large; but there is
with this patch a single place where all relevant CONF parameters can
be looked up and passed into the credential providers.
