Code Issues Proposed changes

Apply workaround to host_info serialization test

Browse Source 
Random failures started appearing in the gate with the following
pattern:

    testtools.matchers._impl.MismatchError: !=:
    reference = HostInfo(plugin_info=[HostPluginInfo,HostPluginInfo])
    actual    = HostInfo(plugin_info=[HostPluginInfo,HostPluginInfo])

This change attempts to work around the issue by adopting the same
workaround as implemented in the VIF tests.

Note that the host_info class is currently largely stub code for an
unimplemented negotiation interface.

# Copied from test_vif.py:
#
# The __eq__ function works by using obj_to_primitive()
# and this includes a list of changed fields. Very
# occassionally the ordering of the list of changes
# varies, causing bogus equality failures. This is
# arguably a bug in oslo.versionedobjects since the
# set of changes fields should not affect equality
# comparisons. Remove this hack once this is fixed:
