[Feature Request] allow repeating elements in list

[AsaphLightricks]

I tried finding someone with a solution to my problem but i couldn't find any issue similar to this. So this is a question / feature request:

🚀 Feature Request

allow repeating an element in a config, for example, for this directory tree:

config
   |-- lights
          |--  point.yaml
          |-- directional.yaml

and this config:

lights: 
  - point
  - point
  - directional

should result in:
{'lights': {'point': ..., 'point': ..., 'directional': ...}}

but currently i'm getting: (hydra v1.2.0)
{'lights': {'point': ..., 'directional': ...}}
missing one of the point lights.

Motivation

as in my example, i would like to indicate that i want to have 2 point lights, and 1 directional light.

Is there a syntax for that that i'm missing?

Note that Python dictionaries only allow each key to appear once:

>>> {"point": 1, "point": 2}
{'point': 2}

See #1939, particularly my comment here, for some tips on how to compose a ListConfig (rather than a DictConfig) using Hydra's defaults list.
