Elmclient

Added oslcquery options:
-R - no default selects - specifically for RM this suppresses putting rm_nav:parent is put into the oslc.select
-I - totalize list columns in the results - e.g. a query for modules with oslc.select=oslc_rm_uses returns an entry for each artifact in the module - this option totalizes these so you get a column of counts of list length - example is querying for all modules and getting all uses back too: -s oslc_rm:uses,dcterms:title -q rdm_types:ArtifactFormat=jazz_rm:Module
-Q - supporess name resolution - means no pre-loading of types, and no post-conversion of URIs to names, but that makes things a lot faster for example when using -I to tsimply totalize - cost is that you can't use names in a query and don't get names in the results

Fixed issue with opt-out project in 6.0.6.1 (found using oslcquery)
Batchquery now shows list of failed test numbers
Split out tests.xlsx to test_702.xlsx and test_6061.xlsx because results are different. Some of these are for obvious reasons, such as6061 not supporting searchterms so 0 results, others less obvious such as artifact counts being different for rm_optout_p1. This is based on the Systems Requirement Sample which has presumably changed slightly between 6.0.6.1 and 7.0.2.

Doing some prep for adding config mgmet at least to rm
Other mostly minor changes
