Make compilerRunTimeoutMs a configurable setting (for VSCode extension)

[spencerdearman]

Is your feature request related to a problem? Please describe.
I am trying to run a more complex quantum circuit that requires a timeout for the variable compilerRunTimeoutMs greater than 5 minutes. It would be really nice if this would be configurable such that the estimator could run longer when using the VSCode extension.

Describe the solution you'd like
When running the estimator, perhaps you could pass in an optional argument for compilerRunTimeoutMs. I included a little code snippet of what this could look like:

results = qsharp.estimate( "Testing.TestToRun()", "compilerRunTimeoutMs": **input here** )

Describe alternatives you've considered
I built the package from source and I edited the locations of compilerRunTimeoutMs to get the result I wanted but it is a bad solution and not as simple as it could be.

I played around with adding this and hit some other issues. Basically, for any action that spins up both a webview and a compiler worker to do the work for it (resource estimation, histogram, circuit visualization, etc.), if the user closes the webview panel before it's done running, that should cancel/terminate the worker.

With that in mind, we probably don't need a timeout at all in these scenarios. We should just let it run and the user can just close the in-progress panel if they want to cancel. Fixing some of the issues here and using this approach might be cleaner than adding new timeout settings.
