metadata service should be setting the objects indirection_api

[Nikola Đipanov]

Ia12f48227eb2380f5da93313cd4045577d8857c9 introduces objects in the metadata service, and metadata is supposed to be using the conductor, so we need to make sure we set the nova.objects.base.NovaObject.indirection_api to conductor in the metadata service.

    Set objects indirection API in metadata service

    Commit Ia12f48227eb2380f5da93313cd4045577d8857c9 introduces objects in
    the metadata service.

    As metadata service is supposed to be using the
    conductor service for it's database access, we also need to set
    nova.objects.baseNovaObject.indirection_api global to point to the
    conductor API so that the object actions will be done by RPC to
    conductor.
