Allow to assign owners to multiple labels

[rusty-key]

Sometimes we have closely related projects, and their owners are the same. This leads to duplications like this:

      {
        "label": "Project 1",
        "owners": [
          "rusty-key",
          "khady"
        ]
      },
      {
        "label": "Project 2",
        "owners": [
          "rusty-key",
          "khady"
        ]
      },

It would be nice to be able to set owners for multiple projects at once:

      {
        "labels": [
          "Project 1",
          "Project 2"
        ],
        "owners": [
          "rusty-key",
          "khady"
        ]
      },

It might be nice to automatically include 'sub-labels' (which aren't a first-class GitHub feature, but many teams use) automatically? Or provide a wildcard type of thing?

For instance, instead of separate entries for

"labels": [
   "Product / Internal / A",
   "Product / Internal / B",
   "Product / Internal / C",
   "Product / Internal / D",
   "Product / Internal / E",
],

… just being able to do …

"labels": [
   "Product / Internal / *"
],

original request taken care of by ead0550
@ELLIOTTCABLE please create separate issue

[rusty-key]

@rr0gi, my request was about OR logic, ead0550 implements AND.
This was requested as well in internal discussion, but I think we should keep this issue open, or "WONTFIX" it

[rr0gi]

I think we want to fix it, but looks like we are pushing json config format too far
