Why is this adding a new bot to main waterfall without CQ coverage?

I recommend we keep it in FYI.

[Will Harris, 2016/03/25 19:38:13]

I'm not sure the "Chromium Win 10" bot on chromium.fyi even uses this
configuration - at least I couldn't find the place that wires the two together.

tbh I think this was always meant to be in the other python file?

I'll keep looking. A lot of this is unfamiliar to me.

[Dirk Pranke, 2016/03/28 22:17:13]

Per the email discussion, we agreed that we'll add this to the main CI waterfall
(chromium.win) w/o matching CQ coverage, but provide an optional trybot.

Acknowledged.

change this to 'chromium_apply_conflig': ['mb', 'ninja_confirm_noop']

so that we will use the src-side MB wrapper and the configs in mb_config.pyl,
and thus switch to GN.

Done.
