Respect configured cred provider in scenario utils
This commit fixes the scenario util classes to actually used the
configured credential provider. Previously these classes were making
a bare call to Manager() to setup the clients. However without passing
it credentials to use Manager tries to use credentials from the config
file regardless of whether tempest is configured using the old config
options for credentials. (it ignores the accounts.yaml or tenant
isolation settings)
