In automation, we install `ffmpeg` as part of `mach browsertime
--setup` in the browsertime toolchain task. Those tasks run on Linux
64 from within AWS, and most of the hosts we hit (intermittently) deny
AWS traffic. Let's just use github.com in automation (and locally),
for all platforms, which will agree with upcoming fetch tasks.

This will allow mozharness tooling, which does not run through `mach`,
to fish these paths.

In browsertime.zip we should have:
browsertime/
package.json
package-lock.json
node_modules/
.bin/
browsertime -> ../browsertime/bin/browsertime.js
browsertime/
...
The idea is that we'll fetch browsertime.zip in a generic-worker
environment and be able to run Node.js from within the top level
browsertime/ directory.

browsertime depends on a few architecture and OS specific packages:
- sharp (libvips)
- geckodriver
- chromedriver
Our toolchain task packages up `tools/browsertime/node_modules` and
we'd like to use the resulting toolchain archive across all of our
test platforms. Since in automation we don't require sharp (which is
only used for screenshotting), and we provide `geckodriver` and
`chromedriver` at the task level, the simplest way is to make these
`optionalDependencies` at the NPM level and not install them in our
toolchain task.

If `./mach browsertime` runs browsertime with a globally-installed node, due to
an existing bug in [execa][1], the wrong Python will be executed. We now
specify the full path of the Python binary we wish to use (via the `PYTHON`
environment variable that our fork of browsertime supports) and avoid this
issue altogether.

Changes include a fix for visual metrics calculations on desktop, and appending visual metrics information to gecko profiles.
Additionally, add the browsertime-results directory to gitignore.

Under the hood, browsertime invokes a certain `visualmetrics.py`
script. That script depends on `ffmpeg` and ImageMagick's `convert`,
`compare`, and `mogrify` commands. It also depends on certain Python
packages.
So this installs those dependencies, and then wires up the evaluation
environment such that `./mach browsertime` can find the dependencies.
It also adds a `./mach visualmetrics` command for processing a
captured MP4 file in the same way that browsertime processes such a
file.
In order to avoid downloading dependencies multiple time, the existing
artifact cache is extracted. This is a small first step towards [Bug
1526021](https://bugzilla.mozilla.org/show_bug.cgi?id=1526021), which
might want to use this artifact cache as well.
At this time, hashes and filesizes are not verified. During
development, the upstream files changed multiple times, and it's not
worth being completely locked down while experimenting with this
functionality. If we start running this code in automation or in more
sensitive environments, we can build fetch tasks and TC indexes to
streamline the artifact gathering process.
It is expected that a future mach command will want to invoke
browsertime without suffering the overhead of invoking Python (and
mach, which is itself bulky) so a nod is given to exposing the
relevant environment pieces.
During testing, it was discovered that [MozillaBuild doesn't ship
git](https://bugzilla.mozilla.org/show_bug.cgi?id=1503028), so that
git repositories can't be used out-of-the-box on Windows. So instead
we use a [tarball link from github.com/$USER/$REPO/tarball/$COMMIT-LIKE](https://github.blog/2008-03-03-tarball-downloads/).

[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.
