[noop] expected that metadata_workers set to "4" but it is set to 2

[Nikita Karpin]

Upstream patch https://review.openstack.org/#/c/383690/ switches nova-api to usage of os_workers fact and therefore breaks Fuel Noop tests:

FAILED openstack-controller/openstack-controller ubuntu16 neut_vlan.vmware.glance-primary-controller
  passed should compile into a catalogue without dependency cycles
  passed should configure region name in cinder section
  passed should configure RabbitMQ Heartbeat parameters
  failed should declare correct workers for systems with 4 processess on 4 CPU & 32G system (expected that the catalogue would contain Class[nova::api] with metadata_workers set to "4" but it is set to 2)
  failed should configure workers for nova API, conductor services (expected that the catalogue would contain Nova_config[DEFAULT/metadata_workers] with value set to 4 but it is set to 2)
  passed should configure default_log_levels
  passed nova config should have use_stderr set to false
  passed nova config should have report_interval set to 60
  passed nova config should have service_down_time set to 180
  passed nova config should contain right memcached servers list
  passed should configure cinder_catalog_info for nova
  passed should configure nova with the basics

    Set metadata_workers for nova

    Earlier metadata_workers option was set to processorcount
    fact by default, but with upstream patch [1]
    it will be switched to os_workers fact,
    so in order to keep the same amount of
    nova metadata workers we need to set it directly
    in openstack_controller task.
