[browsertime](https://github.com/sitespeedio/browsertime) is a harness for running performance tests, similar to Mozilla's Raptor testing framework. The Performance Team is using it locally with some success, but we're running a heavily modified toolchain that is challenging to install. This mach command is intended to be leverage for getting more folks able to use browsertime easily. In particular, the version of browsertime that this installs has nalexander's changes to support testing GeckoView-based vehicles. If this approach meets with approval, I'll continue to follow-up with additional configuration and tooling layers to make it even easier to drive GeckoView-based vehicles. I elected to piggy-back install on the eslint installation process, since this is very similar. To that end, I generalized what was there very slightly. I elected not to try to move the existing code into a more obvious shared location, although it might be possible, because it wasn't clear what contexts the existing code would be invoked from. In particular I wasn't certain the code could rely on a complete mozbuild checkout. I did need to ensure the local Node.js binary is early on the PATH; this was an issue I ran into with my initial Node/Yarn prototyping many months ago. At heart the issue is that package scripts in the wild invoke a bare `node` or `npm` command; if there was a culture of invoking $NODE or $NPM, this wouldn't be necessary. There's no harm doing it for ESlint, and it will help the next person who wants to install an NPM package for tooling in this manner.
