[arm-allstar] Link to a node for x minutes then disconnect

[Stephen - K1LNX]

Before I potentially re-invent the wheel, I wondered if something like this
exists in the app_rpt code.

I have a dedicated channelized remote base node and steer it with the BCD
control script. I put our local NOAA weather radio in one of the channels,
and would like the ability to call it up "on-command" for audio.

Ideally, I'd like to call a function that will:

- change channels to my pre-defined WX channel in the CDM radio via the BCD
script
- Playback audio for 2-3 minutes
- change back to my "default" channel after the timer has elapsed and
disconnect

Unless I've missed it, I don't see a function in app_rpt to facilitate this
behavior? So that left me thinking of options, and I am looking to see if
anyone has any other ideas:

- use my controller (SCOM 7330) to send a DTMF command to call a script,
run on a timer, then send another DTMF command to disconnect it (this would
be easiest, but my preferred use to call scripts and functions is to use
MDC instead which the SCOM does not support)

- write a shell or python script to handle this

- hack something together in the dialplan, I think I might be able to
leverage the autopatch function for this, but haven't looked into it yet.

Looking for ideas if anyone has any, and perhaps I'm overthinking this
which I'm known to do on occasion ;)
