Code Issues Proposed changes

Expose conductors: api

Browse Source 
This patch implements API part to the feature of exposing conductors
information.

A new API object Conductor is added to provide endpoints below:

* GET /v1/conductors for listing conductor resources
* GET /v1/conductors/{hostname} for showing a conductor

V1 endpoint discovery and default policy are updated.

A conductor field is added to Node API object, which returns in
/v1/nodes* related endpoints.

Considering patch size and microversion conflicting with other api
patches, api-ref would go in another patch if no strong opinions.

Task: 28064

Adds support to retrieve the information of conductors known
by ironic:
* a new endpoint ``GET /v1/conductors`` for listing conductor resources.
* a new endpoint ``GET /v1/conductors/{hostname}`` for showing a
conductor resource.
Adds a read-only ``conductor`` field to the Node, which represents the
conductor currently servicing a node, and can be retrieved from following
node endpoints:
* ``GET /v1/nodes?detail=true`` or ``GET /v1/nodes/detail``
* ``GET /v1/nodes/<node_ident>``
* ``POST /v1/nodes``
* ``PATCH /v1/nodes/<node_ident>``
