We don't plan to support NITB or old openbsc repo in 201705 for now.
Build the core images instead of the NITB, which since recently don't
contain osmo-nitb or other binaries from the openbsc repo, only osmo-pcu
and osmo-bts are included.
This is not tested and will be debugged on the server. Begin to
automate the on-server setup so we can make this a self-service
without much user interaction.
Create a Makefile that does the lifting of setting up the config
as it is done on the system. Handles the creation of the .ssh/config
for upload.
In the past upstream poned on such master Makefiles but as we
customize our build environment quite a bit it probably makes
sense and reduces the clone+set-up to two calls.
