Task #10339 and 10607: ltacp does not overwrite globus environment variables anymore, but expects them to be available in the environment (so other users like Jorg/Sander can use ltacp in their environment

Task #10339: split MoMQueryService into client and server part. Made LTAIngestAdminServer only dependent on MoMQueryServiceClient so we don't run an extra momqueryservice on the lexar3/4

Task #10339: it's not exactly clear what happened to the 2_20 branch, but many changes in LTAIngest from 2_19 were lost. Did a manual merge from 2_19 branch into this 2_20 branch for LTAIngest and SAS/DataManagement

Task #10339: applied patch from 2.19: when setting status and message, set status first and then message, otherwise mom can't handle it.

Task #9931 #10057: merged feature branch ^/branches/ltaingest-Task9931 into LOFAR-Release-2_19 branch
