Multiple Monitor Sinks + Remove monitor field from case

[lukelowry]

Summary

Ability to make a monitor in the *.solver.json and collect component monitor data based on some regular expression

Rationale

Having the monitors defined in the *.case.json is not intuitive and really difficult to use. Having a wildcard/regex in the .solver.json and beign able to colelct output into different files is what we need.
