Matt Riedemann 4a55e260a4 Remove [scheduler]/host_manager config option
While this option itself was not technically deprecated,
the option only had two choices and the "ironic_host_manager"
choice has been deprecated since Queens:

  Iebc74a09990dcda8cf0ee2a41f9ae1058d2a182a

And was removed in Rocky:

  I695b250c82c8dcedcd8e2bee00c56bb2df19212c

Since the host_manager option only had one choice, which
is also the default, it's not really an option anymore and
we can simply remove it. Setting it will have no effect
so there should be no upgrade impact for its removal.

upgrade:
- |
The ``[filter_scheduler]/use_baremetal_filters`` and
``[filter_scheduler]/baremetal_enabled_filters`` configuration options
were deprecated in the 16.0.0 Pike release since deployments serving
baremetal instances should be `scheduling based on resource classes`_.
Those options have now been removed.
Similarly, the ``ironic_host_manager`` choice for the
``[scheduler]/host_manager`` configuration option was deprecated in the
17.0.0 Queens release because ``ironic_host_manager`` is only useful when
using ``use_baremetal_filters=True`` and ``baremetal_enabled_filters``.
Now that those options are gone, the deprecated ``ironic_host_manager``
host manager choice has also been removed. As a result, the
``[scheduler]/host_manager`` configuration option has also been removed
since there is only one host manager now and no need for an option.
Remember to run ``nova-status upgrade check`` before upgrading to
18.0.0 Rocky to ensure baremetal instances have had their embedded
flavor migrated to use the corresponding ironic node custom resource class.
