machenbach / sergiyb - is there some historic reason I've forgotten why you'd have a different priority here? Or a reason to use the chrome pool other than convenience?

Priority difference is strange. Will change V8.

Using the chrome pool is historical and not trivial to just switch. We benefit from having our core working time in EMEA time zone, which is somewhat complementary to chrome.

In order to split the pools, we'd need our own capacity estimates and MP leases for high/low times. We can work on this as soon as some dev cycles are free.

(V8 label makes this bug visible in our bug queue)

[V8] Use correct swarming priority on V8 tryserver

Previously, V8 had a code path to allow manual tryjobs with higher priority
than CQ. After the luci migration, the path became dead code and all CQ
tasks were run with too high prio.

This removes the old logic and uses the same priority as in Chromium for
all tryjobs. The requester field seems to be not set anymore but seems to
also not be needed for anything. Neither is the purpose tag. The user
property is None in production tasks, so it's removed here, too.
