Bootstrapping automatically downloads new Rust and Cargo snapshots
as needed into versioned directories,
but do not remove now-unused versions.
This is the desired behavior for `git bisect` to be usable.
However, this means that old version keep accumulating, taking up disk space.
This adds a mach command to remove snapshots other than the ones
currently being used.
It is never run automatically.
To be safe, the command defaults to only printing what would be removed,
and only removes stuff when run with a `-f` argument.
Since default argument to params is None, concatenating it with a
list will raise an error. This behaviour prevents `./mach rustc`
to be called when system-rust is defined in .servobuild.
Currently it will only work when followed by an argument, i.e.
`./mach rustc -arg`.
Testing this patch: `./mach rustc` should not raise an error.

When running commands through Registrar.dispatch, mach does not behave
in the same way it would as if it were running through the command line.
Defaults normally provided through a combination of @CommandArgument and
argparse magic are ignored.
I have some ideas as to how to fix this, but until then, this will allow
`./mach test` to run through test-unit properly.
There are none, but the contenttest program fails with:
```
task '<main>' panicked at 'Required option 'source-dir' missing.', ../../tests/contenttest.rs:48
```
Minor change, added unit test filter to components so that ./mach test-unit [test-filter] works in line with documentation.
I'd personally like to also make filters on the components as well as the tests. This would change the interface (probably to ./mach test-unit [component-filter] [test-filter]), but change is NOT in this pull request.
`./mach test-ref` no longer eats the first "-" prefixed argument for test name filtering, instead using an explicit "--name" argument. This should avoid any potential confusion when passing down arguments to servo.
Also allows for ./tests/ref to be included (and trimmed away) for tab completion convenience (`./mach test` has also been updated to take advantage of this when inferring tests from file paths).
(fixes#4091)
Usage Example:
```
$ ./mach test tests/wpt/web-platform-tests/dom/interfaces.html
0:00.27 LOG: MainThread INFO Using 1 client processes
...
```
Note that while there is no functionality for `test-ref` to accept
individual files, `./mach test tests/ref` will still trigger `test-ref`.
