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).

fixup for 203927d9

In the compilation, there were many errors regarding rpath in Fedora
with the explanation message below. So I put the minimum to change the
error into warning.

*******************************************************************************
*
* WARNING: 'check-rpaths' detected a broken RPATH OR RUNPATH and will cause
*          'rpmbuild' to fail. To ignore these errors, you can set the
*          '$QA_RPATHS' environment variable which is a bitmask allowing the
*          values below. The current value of QA_RPATHS is 0x0003.
*
*    0x0001 ... standard RPATHs (e.g. /usr/lib); such RPATHs are a minor
*               issue but are introducing redundant searchpaths without
*               providing a benefit. They can also cause errors in multilib
*               environments.
*    0x0002 ... invalid RPATHs; these are RPATHs which are neither absolute
*               nor relative filenames and can therefore be a SECURITY risk
*    0x0004 ... insecure RPATHs; these are relative RPATHs which are a
*               SECURITY risk
*    0x0008 ... the special '$ORIGIN' RPATHs are appearing after other
*               RPATHs; this is just a minor issue but usually unwanted
*    0x0010 ... the RPATH is empty; there is no reason for such RPATHs
*               and they cause unneeded work while loading libraries
*    0x0020 ... an RPATH references '..' of an absolute path; this will break
*               the functionality when the path before '..' is a symlink
*
*
* Examples:
* - to ignore standard and empty RPATHs, execute 'rpmbuild' like
*   $ QA_RPATHS=$(( 0x0001|0x0010 )) rpmbuild my-package.src.rpm
* - to check existing files, set $RPM_BUILD_ROOT and execute check-rpaths like
*   $ RPM_BUILD_ROOT=<top-dir> /usr/lib/rpm/check-rpaths
*
