WIP: Changeover most DFDLTestSuite invocations to Runner

[IanCarlsonOwl]

Tweak the interface to the Runner object, as well as creating a RunnerOpts object to handle the multiple combinations of parameters used by various tests without compromising the ability to default parameters not under test.

DAFFODIL-1300

[IanCarlsonOwl]

There are a number of calls to DFDLTestSuite still outstanding, but I wanted to get this much in front of others for a sanity-check, and to ensure it builds on all of our target systems.

Closed as inactive. Ticket DAFFODIL-1300 is closed. If there is other functionality here being worked on a new JIRA ticket is needed.
