Remove remaining references to `hm9000_noop`
Nginx logs X-Request-Id (now set by the gorouter)

This change is in place of https://github.com/cloudfoundry/cf-release/pull/302
by @sykesm because `nginx.conf.erb` moved from `cf-release/jobs/cloud_controller_ng/templates/nginx.conf.erb`
into `cloudfoundry/cloud_controller_ng/bosh-templates`

Prevent CC from creating orphaned clients in UAA: ServiceDashboardClients can now exist without an associated broker and can be re-used

- if creating or updating a Service Broker fails (due to UAA client creation errors or any other reason), a ServiceDashboardClient is still created in the DB for each client created in UAA.
- upon a subsequent ServiceBroker create or update, any dashboard clients existing in the db with a uaa_id present in the catalog will be associated with the broker.
