This patch adds two options in fetcher_keystone to filter which tenants
should be rated:
ignore_disabled_tenants (Default=False)
ignore_rating_role (Default=False)
In our case we currently have 2k projects (growing) and we want to rate
all active projects, so checking the role rating is useless and consumes
resources for nothing. Besides, cloudkitty rates projects regardless if
there are enabled or disabled which is also useless and consumes
resources in our case.
