Matt Riedemann c99fc64271 Deprecate the IronicHostManager
The use_baremetal_filters and baremetal_enabled_filters options
along with the ExactRamFilter, ExactCoreFilter and ExactDiskFilter
filters were all deprecated in Pike:

  I843353427c90142a366ae9ca63ee4298b4f3ecd4

The IronicHostManager is configurable and relies on those options,
so if those options are deprecated then the IronicHostManager should
also be deprecated.

The sticky part with this is going to be filters that don't work with
ironic nodes today, like the NUMATopologyFilter, so a note is left
in the use_baremetal_filters option code to remind us that we can't
likely remove any of this until all filters work with ironic nodes.

The `IronicHostManager` is now deprecated along with the
``[scheduler]/host_manager`` option of ``ironic_host_manager``.
As of the 16.0.0 Pike release, the ``ExactRamFilter``, ``ExactCoreFilter``,
and ``ExactDiskFilter`` scheduler filters are all deprecated along with
the ``[scheduler]/use_baremetal_filters`` and
``[scheduler]/baremental_enabled_filters`` options. Deployments should
migrate to using resource classes with baremetal flavors as described in
the ironic install guide:
