It's impossible to filter nodes by provision_state via API

[Dmitry Tantsur]

In standalone case using "associated" filter no longer makes sense. Also, it might be useful to filter nodes for different states, e.g. in Tuskar UI people want to know nodes on inspection.

    Filtering nodes by provision state

    Add support for filtering nodes by provision state in the
    node-list command. For provision states with spaces, like
    'wait call-back' ironicclient will encode it to %20 in the
    uri.

    And bump the default version to 1.9.
