Script to generate buildbot json for both the perf waterfall and fyi
waterfall.

chromium.perf.json: This file should not change in overall content
although some of the ordering may be off.  I have also explicitly
set the shards for Win 7 Intel GPU Perf given the format my script
expects, which is the same as the current json file which doesn't
specify a shard.

Note: I have removed entries for bots that are not longer on our waterfall.  These include Win 7 Low-End Perf, Mac 10.9 and Mac 10.8.  This is simply cleanup and doesn't impact any functionality.

chromium.perf.fyi.json: This file is new and doesn't have any
configuration yet that will actually read this file.  The next
step is to trigger the jobs locally before I change the fyi recipes
to read from this json file.  Note: telemetry_perf_tests will be the
name of the gn target in a follow up cl.  Note that this file
will probably change as I iterate on getting the perf tests swarmed.
