Use QG mapper to replace code in various places

[jhakala]

The QG mapper can be used to replace the logic at:

levelOneHCALFM/src/rcms/fm/app/level1/HCALMasker.java

Line 192 in af4e027

Group fullConfig = level2group.rs.retrieveLightGroup(level2.getResource());

levelOneHCALFM/src/rcms/fm/app/level1/HCALMasker.java

Line 293 in af4e027

Group fullConfig = level2group.rs.retrieveLightGroup(qr.getResource());

levelOneHCALFM/src/rcms/fm/app/level1/HCALlevelTwoEventHandler.java

Line 642 in af4e027

XdaqExecutiveResource qrTAparentExec = ((XdaqApplicationResource)taResource).getXdaqExecutiveResourceParent() ;

Also, the new parameter QG_MAP can be used to replace AVAILABLE_RESOURCES.
