This also solves the problem that specifying x96-64 as generic
optimisation works for -march=x86-64 but not for -mtune.

Remove the -march=soandso and just pass soandso as build arg
and take care of setting the -march and -mtune parameters in
the Dockerfile.

Fix a bug where parts of the image are always compiled with
-march=haswell setting.  This breaks even the compilation of lofar-base
further down the line when executed on a non-haswell build host.

SW-907: copied the gitlab-ci.yml file and Docker/lofar-ci directory from master, so we can run the gitlab CI/CD pipeline on the release branch as well

2fec5b36 SW-837:  Add parameters that checkout aoflagger as shallow copy

SW-833: added git python python3 g++ make packages so the image can be build (no need to remove git and python in blitz command)

If the library is missing, then the DP3 interpolation plugin
is not built.  This is a nasty and hidden build time dependency.
