Compute JVM Memory-Configuration Based on Hosting-Instance's Available RAM

[ferricoxide]

Problem Description:

Currently, the SupportFiles/agent-userscript.ps1 file statically sets -Xmx to 256MiB. It may make more sense to derive a value based on the agent-host's available memory configuration (or leave wholly unset to accept the agent-defaults).

Similarly, vendor recommendations for heap-size are to set -Xms to half -Xmx. In current script, -Xms does not appear to be set at all.

Expected Behavior:

JVM will be tuned to align well with hosting-instance's available memory

Actual Behavior:

JVM is statically-set
