Rewrite MeasureManager in C++

[jmarrec]

Enhancement Request

Even in the labs subcommand, the MeasureManager is purely Ruby, so you can't use it to compute arguments for a Python Measure.

Detailed Description

OpenStudio/src/cli/MeasureUpdateCommand.cpp

Lines 369 to 389 in f4f51c3

	void MeasureUpdateOptions::execute(MeasureUpdateOptions const& opt, ScriptEngineInstance& rubyEngine, ScriptEngineInstance& pythonEngine) {
	opt.debug_print();
	if (opt.server_port > 0) {
	const auto measureManagerCmd = fmt::format(
	R"ruby(
	require 'measure_manager_server'
	port = {}
	server = WEBrick::HTTPServer.new(:Port => port)
	server.mount "/", MeasureManagerServlet
	trap("INT") {{
	server.shutdown
	}}
	server.start)ruby",
	opt.server_port);
	rubyEngine->exec(measureManagerCmd);

Possible Implementation

We have the buildings blocks in place to compute arguments already in the MeasureUpdateCommand::getAndUpdateMeasure. But we'd need to write an HTTP server in C++. We have cpprestsdk that we already use for RemoteBCL. boost asio is another option, so is Poco.

I scoped it out, implemented a basic http server with cpprestsdk, looks like it wouldn’t be a daunting task

I agree that a small http server using what we already have, cpprestsdk, is a good path.
