- Update registry to new production registry

- Create /etc/re6stnet if needed

This reverts commit 097e1cd0.

This is not working because of dependencies on newer libc6 and
libstdc++6.

init-sdr and init-enb scripts should be ran by slapos. That way if eNB
and gNB services are stopped in slapos sdr driver will not be loaded,
which allows to use lte stack manually without interference.

This is to prevent the "The 'wheel' distribution was not found" error

Use the same value as for vifib servers.

This variabe was always True.

since we are running in multiple sites, we need tunnels between the
sites. Let re6st handle this as usual with tunnels.

The configuration of the data disk will be done manually (especially
since it may require GPT partition table now).
