Salt-key can control minion keys on salt syndic nodes

[DesireWithin]

Is your feature request related to a problem? Please describe.
I want to use restapi to control minion keys on salt syndic.
The most common case is when a server is decommissioned. I also want to delete its key on salt syndic.
But I don't know who is this server's master. So salt-key can also control salt syndic is much more convenient

Describe the solution you'd like
salt-key can issued command to salt syndic, just like salt command do.

Describe alternatives you've considered
My workaround is run salt-key command on each salt syndic.
I'm using local client, create a nodegroup named masters contains all syndic nodes.
So command will be something like this:

curl -sS localhost:8000/run \
    -H 'Accept: application/x-yaml' \
    -H 'Content-type: application/json' \
    -d '[{
        "client": "local",
        "tgt": "masters",
        "tgt_type": "nodegroup"
        "fun": "cmd.run",
        "kwarg": {"cmd: 'salt-key -d  salt_keys -y'"}
        "username": "saltdev",
        "password": "saltdev",
        "eauth": "auto"
    }]'
