API to assign profiles to nodes

As the result of advanced profile matching we need node capabilities updated with one profile. Previously, advanced matching could end up with several profiles stored in /properties/inspector-profiles.

API POST /v1/match?provide=true|false
Selects all nodes from ironic database and tries to assign profiles.

Request body:

 {
   "profiles": [
        {"profile": <PROFILE>,
         "count": 1,
         "required": true},
        {"profile: <PROFILE2>,
         "count": "*"}
    ]
 }

count being a number means matching exact number of nodes, count being "*" means all matching nodes that were not assigned a profile earlier (thus order matters). required=true (default is false) will make the process fail without doing anything, if no nodes matched this profile.

One profile can repeat several times, e.g.:

 {
   "profiles": [
        {"profile": compute,
         "count": 1,
         "required": true},
        {"profile: control,
         "count": 1,
         "required" true},
        {"profile": compute,
         "count": "*"},
    ]
 }

This will require one compute node, one control node, and will assign "compute" profile to all remaining nodes matching this profile.

If provide is true (default is false), matched nodes will be transitioned to "available" provision state.
