Bug: heap size maximum in testing environment lower than typically used in production

[dwr-zroy]

Issue

When running cucumber tests, the JVM is launched with a heap size that is much smaller than is typically used when running the models "in the wild".

wrims-engine/wrims-comparison-test/src/test/java/gov/ca/water/wrims/comparison/utils/ComputeTestUtils.java

Lines 20 to 23 in a5448dd

	public static final String XMX_PARAM = "-Xmx4096m";
	public static final String XSS_PARAM = "-Xss1024K";

Proposed Fix

A more practical memory limit is around 12 GB. At DWR we have a "help" page where the recommend value is currently 100,000 MB 😆.

Other context

WRIMS 2 has had changes since we "forked" where this defaults to 60% of the systems available RAM. The user can still modify this through Run > Option > Allocated Memory (mb) in the GUI.

This is to correct reduced performance of engine in test env. The scope of this fix will only address compute testing from the WRIMS-Engine.

1. There will be a default memory setting in source.
2. This will be overridden by a system property that can be set via runtime.
3. This will be overridden by a resource file value that allows the memory to be set on an individual test by test basis.
