Update executable location in all monitor scripts

[EdwardSafford-NOAA]

Cmake install places the monitor executables in install/bin or SOURCE_DIR. Update all scripts to find the executables in this location.

The scope of this issue has widened considerably as I've been working through it. I'm going to break things up into smaller units so it can be more easily reviewed. Almost all of these changes are to the "developer" side of the monitors, meaning everything that isn't in the *_Monitor/nwprod directory (manual data extraction, image generation, an utility functions).

It's worth noting that my intention here is not to overhaul the packages entirely. Discussions have begun to develop a new monitoring approach that is both unified (no RadMon, MinMon, etc, just monitoring) and easily extended/modified (python based, yaml driven).

These are the major changes that are required at this point:

• Add a package wide configuration file that will largely replace the 4 monitors' configuration files. Specific config files will still be needed for individual monitors but will be greatly reduced in size and complexity.
• Add full support for orion.
• Remove all wcoss_dell and wcoss_cray specific items.
• Update executable locations (all in GSI-monitor/install/bin).
• Use hpc-stack for all module reference.

I will open new issues for this and work monitor by monitor, beginning with RadMon.

RadMon is set with #14, OznMon is in progress with #27, ConMon is slated for changes with #28 . Accordingly will close this issue as no longer needed.
