Use swarming on experimental memory trybots

Use swarming on experimental memory trybots

With this change they take about 1 hour 25 minutes to cycle.

Next step is likely swarming net_unittests.

1) why not just swarm everything at the same time so we can see the result?

2) please adjust the sharding so that the bot can run in < 40 minutes

how about 10? that way it should finish in under 10 minutes.

for the buildbots, I used a higher multiple for debug vs release for the same
reason

This mirrors what the other trybots used to swarm.

Can I move with smaller steps for now? This bot is not used by anything yet, and
without this patch it'd take even longer to cycle, so this is an improvement.

Can I do that in separate patch? Last time I checked this was mirroring what
other trybots are doing.

other trybots also swarm net?

sure, not trying to slow you down. just wondering if we can make small changes
to this patch so that the data we start collecting is more representative of
where we want to be

well, we can't compare release trybots to asan :) the former are much faster.

Okay, PTAL.

btw I forgot to add that content's tests are already swarmed, so that's an easy
thing to turn on. should save about 8 minutes and bring the bot very close to 40
minutes :)
