SW-658: removed obsolete datetime conversions now that these are automagically converted in the from/tobus

SW-658: replaced SOAPpy by python3 compliant package pysimplesoap. Adapted ingestmomadapter to use pysimplesoap. Added test t_ingestmomadapter to tests soap functionality.

This includes:
- python executable -> python3
- Help texts
- #! specifications
- Shell scripts

SW-516: made LTAIngestTransferServer code python3 compliant. Fixed tests. Used new TemporaryQueue class for qpid testing

ROHD-1592: added option to create a minimal/unspecified SIP in case the MoM SIP is invalid. Used it for WTG-verification-DMO project.

SW-0: moved the cep4_utils.py file from QA to LCS/PyCommon, and fixed references. Needs to be adapated in https://svn.astron.nl/LOFAR/branches/adder-Task10079 as well.

SW-0: only monitor outgoing traffic to LTA sites, not all outgoing traffic. As a (desired) consequence, outgoing LTA traffic is now allowed to take precedence over internal traffic.
