hosts.py missing from novaclient

[Tracy Jones]

after installing the latest openstackclient i get the following

openstack host list
'Client' object has no attribute 'hosts'

looking further i see that hosts.py is missing from novaclient/v2

it installed python-novaclient==10.1.0

just found it was deprecated.

[Matthew Edmonds (edmondsw)]

os-hosts has been deprecated, but it should still work for microversions <2.43

$ env | grep OS_COMPUTE
OS_COMPUTE_API_VERSION=2.42
$ openstack host list
'Client' object has no attribute 'hosts'

trace is:

openstackclient version 3.14.0
novaclient version 10.1.0

[Takashi Natsume (natsume-takashi)]

os-hosts CLIs and python API bindings was removed in the following patch.

https://review.openstack.org/#/c/532989/

In the releasenote, it suggests alternatives.

    * ``nova host-describe`` - superseded by ``nova hypervisor-show``
    * ``nova host-list`` - superseded by ``nova hypervisor-list``
    * ``nova host-update`` - superseded by ``nova service-enable`` and
      ``nova service-disable``
    * ``nova host-action`` - no alternative by design

So the following commands can be used in the openstackclient instead of the removed commands.

- openstack hypervisor show
- openstack hypervisor list
- openstack compute service set

IMO, it should be fixed in the openstackclient side.
(Fix code and/or documents.)
