Initial class creds creation in test base class

Each test class may now define at class level which credentials
are needed, and they will be allocated automatically by the base
class. To start using this a test class that requires network
resources must implement the setup_credentials method and
define the required resources before super is invoked.

In this patch this only affects the creation of credentials
as defined in the various base classes. Other tests will be
migrated as part of the resource-cleanup bp. Note that this
changes baremetal, identity and orchestration tests to
honour the tenant isolation settings.

Partially-implements: bp resource-cleanup
