Add support for osmo-bts-octphy
Specific parts for this class:
- Runs osmo-bts-octphy binary, that requires CAP_NET_RAW capability
because it uses an AF_PACKET socket.
- As a consequence, it must use the previously added APIs to set the
capability and modify the RPATH of the binary before launching it. These
APIs require extra host setup and installed dependencies that will be
documented soon in osmo-gsm-tester manual.
- A num_trx() helper method is added because the binary requires that
parameter.
- A allocate_phy_instances() is added to help build/fill the conf
dictionary to be used in the tmpl to be able to easily set up trx, phy
and insances.
A config to use a osmo-bts-octphy at full power is used (4 trx) is added
in this commit to show how can it be configured. However our
current license only has support to use 1 TRX, and so next commit drops
most configurations to simplify the setup to use only 1 TRX.
