Subject: [PATCH] Add 'is_available' function

Resolves the following warnings seen in the likes of Neutron:

  opt/stack/neutron/neutron/common/eventlet_utils.py:28:
  DeprecationWarning: Please provide `is_available()`
  function in your custom Eventlet hub <module 'oslo_service'

  It must return bool: whether hub supports current platform. See
  eventlet/hubs/{epoll,kqueue} for example.

Since we're simply taking the default hub provided by eventlet and
overriding a single attribute, we will always have support so set the
attribute.
