Wander Lairson Costa cd15766fd6 Bug 1333167: Add extra try options to taskcluster. r=dustin a=jmaher
We add the following command line options to Taskcluster try syntax:

--spsProfile: enable profile mode.
--rebuild-talos <N>: retrigger talos tests N times.
--setenv <VAR>=<val>: add extra environments variables.
--tag <TAG>: run tests only the tag TAG.
--no-retry: doesn't retry failed jobs.

We have a chicken-egg problem, as we first generate the full task graph
and then parse the try message. But the graph generation step needs to
know the try message to process the aforementioned options. The
solution is to parse the message before graph generation and then
pass the command line options to the transforms. Then, each transform
can look at the option that interests it and process it accordingly.

The message parse function is configured in kind.yml, which gives some
flexibility for future implementations of alternative syntaxes.
