Eliminate duplicated cvmfs stratum 1 configuration

Some of the stratum1s are not included because they were not in failover or distance configuration:

ERROR: bnl-cvmfs01 does not have awstats group
ERROR: bnl-cvmfs02 does not have awstats group
ERROR: unl-hcc-cvmfs1 does not have awstats group
ERROR: unl-hcc-cvmfs2 does not have awstats group
ERROR: unl-hcc-cvmfs1-1 does not have time zone
ERROR: unl-hcc-cvmfs2-1 does not have time zone
ERROR: unl-hcc-cvmfs1-2 does not have time zone
ERROR: unl-hcc-cvmfs2-2 does not have time zone

The configuration output looks like this:
