Here browser_type is still forced, but it is for the new virtual test suite
configuration only.

Another choices are:

1. to issue warning here, and modify bot code to pass
--browser=content-shell-release for blink_perf.layout_full_layout and
blink_perf.svg_full_layout. The con is that the bot must know the names of
specific test suites that need --browser=content-shell-release.

2. based on 1, but add blink_perf_full_layout.py which adds
blink_perf_full_layout.layout and blink_perf_full_layout.svg suites, and let the
bot pass --browser=content-shell-release for blink_perf_layout_full.* suites.

wdyt?
