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.
(cherry picked from commit 63e2e0bc95f83c10d8af0cd17b675f3761b8c69b)
