Add stream request

[patrickelectric]

As mavp2p, we should add stream requests to start receiving messages from the autopilot

Current BlueOS master uses the streamreq-frequency arg, which is not implemented and is exactly what we are missing here.

/usr/bin/mavp2p \
  udps:127.0.0.1:8852 \
  udpc:192.168.2.1:14550 \
  udps:0.0.0.0:14550 \
  tcps:127.0.0.1:5777 \
  udps:0.0.0.0:14660 \
  udpc:127.0.0.1:14000 \
  --streamreq-frequency=10

When I first made this CLI, BlueOS master was using streamreq-disable, which I added here just to be able to run mavlink-server without modifying BlueOS.

Retification:

my BlueoS reverted to factory. The current master has the same behavior of the master when I first implemented the CLI, and it was modified here:

So probably this is not what we are missing.
