Feature: Ability to define tags in deployment.yaml

[Dave Chiluk]

It would be nice to be able to define tags in deployment.yaml *(both xpath and trivial ones).

Note: this is different than the specified tag. Each node can already have a specific tag attached to it. Adding in general tag support to the maas section allows for richer xpath tags etc.

The deployment.yaml could look like this:

demo-maas:
  ...
  maas:
    ...
    tags:
      - name: gpu
        comment: 'GPU with clock speed >1GHz for running CUDA type operations.' # optional
        definition: '//node[@id="display"]/clock > 1000000000'
      - ...

Thoughts?

    {
        "comment": "Ceph Nodes",
        "definition": "count(//node[starts-with(@id,\"disk\") and @class=\"disk\"]) >= 8",
        "resource_uri": "/MAAS/api/1.0/tags/9disk/",
        "name": "9disk",
        "kernel_opts": ""
    },

Here's an example of our more complicated xpath tag.
