###### Regular (non-Orchestrator) CQ builders
The starlark config files for builders are organized by builder_group. For
example, the linux builders are in
//infra/config/subprojects/chromium/try/tryserver.chromium.linux.star. These
files have default values set for all builders in each particular file.

tryjob = try_.job(),

orchestrator name + "-compilator", like linux-rel and linux-rel-compilator.
