Code Issues Proposed changes

Add 'is_available' function

Browse Source 
Resolves the following warnings seen in the likes of nova:

    DeprecationWarning: Please provide `is_available()` function in your
    custom Eventlet hub <module 'oslo_service' from
    '../oslo_service/__init__.py'>."

    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.
