    domain name from id lookups return empty

    If the given domain id is not available in the @domain_hash,
    look it up in Keystone and add it to the hash. Do not assume
    the @domain_hash can be populated once. It must take into
    account domains that are created later.
    This consolidates the various bits of code that reset the class
    variables in the provider superclass into spec_helper.rb - we must
    be consistent about resetting the variables to ensure the spec
    tests return consistent results.
