admin: Update admin logout

In order to logout properly without using the astakos' urls, we will use
astakosclient.

More specifically, we will use the 'ui_url' property of astakosclient
that holds the url for the UI of Astakos and we will append to the end
of this url the '/logout' string. The user that requests to logout will
therefore get redirected there.

admin: Replace "snf-" with BACKEND_PREFIX_ID
admin: Add RBAC

The definition of which groups can author actions is kept in the conf
file of admin and has the following structure:

ADMIN_RBAC = {
    'user': {
        'activate': ['admin', 'helpdesk'],
        .
        .
        .
    },
    'vm': {...},
    .
    .
    .
}

That is, the main entry point is ADMIN_RBAC, which is a dictionary. The
first level of this dictionary is the target category of an action, e.g.
user, vm, volume etc. The second level is the action, which points to a
list of groups that can author it.
