Added a general command line parameter "--jvm" to pass Java options t…

…o the test runs and --debug to enable remote debug with default options (#573)

The following examples both enable remote debug during the test run:

./bin/run_tests -s Functional -g functional -d --jvm "-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=50000,server=y,suspend=y"

./bin/run_tests -s Functional -g functional -d --debug
