power_control: add CTRL command for sending default params

There exists a VTY command for sending default power control params,
but so far there was no CTRL counterpart for it.  This patch adds a
SET command 'send-power-control-defaults':

  $ osmo_ctrl.py \
	--host 127.0.0.1 -p 4249 \
	--set "bts.0.send-power-control-defaults" 1

Similar to 'send-new-system-informations', this command takes an
arbitrary dummy value (required for SET), which is simply ignored.
