Should this still be P2? There's no status update at https://luci-migration.appspot.com/masters/chromium.infra.cron/builders/wpt-importer/

This would most likely be migrated together with wpt-exporter ( bug 790570 ).

First step for both of these is to modify the recipe to check the api.runtime.is_experimental recipe attribute, and if the builder is experimental, just do a dry run. Then we'll add the LUCI builder, check that it runs as expected with dry runs and then flip "LUCI is prod". This will make it easy to roll back if something unexpected happens.

luci.infra.cron: connect to migration app

Connect luci.infra.cron to migration app because not all builders were migrated
to LUCI yet.

[WPT import] Add a flag to upload but not submit CL

We used to have only one flag, --auto-update, which controls both
uploading and landing the import CL. This makes testing new setup of the
bot (i.e. LUCI in this case) hard.

This change adds one more flag, --auto-upload, to exercise more steps
(namely uploading and rebaselining), which will be used on the
experimental LUCI builder.

Build looks to be working as intended and matches Buildbot results. Can the LUCI builder be flipped to prod?

Hi Eric, sorry I was travelling in the last two weeks. Yes, could you please flip the switch to set LUCI as prod? Thanks!

[WPT Import] Stop creating CLs on experimental bot

The experimental builds on LUCI have proven to work as intended and we
are flipping prod to LUCI, so we don't need to create CLs from the
experimental bot anymore. This will save some unnecessary try jobs and
reduce the wait time of *-blink-rel bots.

[Import Notifier] Get Monorail OAuth token from luci-auth

The application default credential belongs to the default Swarming bot
account, not the dedicated service account for wpt-importer. As
suggested by LUCI task force, we need to use `luci-auth token` instead.
