fake_trx: introduce CTRL commands for RSSI simulation
Since FakeTRX is a proxy, it basically emulates transceiver for
both osmo-bts-trx and trxcon, hence there are two separate and
independent control interfaces (usually, ports 6701 and 5701).
All simulation commands (see 'FAKE_*') are usually implemented
on both interfaces separately:
- ctrl_if_bb.py - simulation commands affecting Uplink,
- ctrl_if_bts.py - simulation commands affecting Downlink.
This change introduces the 'FAKE_RSSI' command for both CTRL
interfaces in two variations:
- absolute: CMD FAKE_RSSI <BASE> <THRESH>
- relative: CMD FAKE_RSSI <+-BASE_DELTA>
where 'THRESH' affects optional value randomization.
