SW-231: removed LTAIngest's LTA-SIP.xsd and moved sip's LTA-SIP.xsd to new LTACommon package, so they share one LTA-SIP.xsd

SW-231: fixed tests for LTA siplib. When pyxb package is not available on the test/build system, then skip the test with exit code 3

SW-74: non part of SW-74, but had some small tweaks lying around for ltacp to zip the datastream while transferring. This is not used by default, but can be convenient when testing for stalling transfers due to globus-url-copy choking on certain byte patterns in the datastream. gzip alters the datastream, so globus-url-copy should not stall when the datastream is altered by zipping it.

Task #11385: JIRA LSSS-291: use supervisor to restart service when no active session avaible on qpid broker

Task #11385: JIRA LSSS-291: improved overall throughput by running slow small files and fast big files in parallel

Task #11385: mail to seperate to/bcc adresses. only mention 'could not find mail adresses' remark in successful mails

Task #11385: first check if dataproduct is already in LTA, then check for valid sip. If already in lta, do not set status to failed.

Task #11385: check for valid sip before transfer. block dataproducts with invalid sip. various minor performance improvements

Task #11220: use sara's round robin dns to get turl. minor improvements in string replacement using regex

Task #11245: when resubmitting one job file, the whole group is now loaded, so the reports are about the whole group

Task #11242: check if the disk is mounted if a source path cannot be found. If disk is not mounted, transfer should fail normally

Task #11208: from now on, ingest reports dataproducts which failed to transfers as failed to MoM (instead of as 'produced', which had it's reasons, but was very illogical
