[Findit] Function to get a bot's dimensions via swarmbucket api.

Once the 'luci.chromium.ci' bucket is set-up, this new function will
allow us to get the dimensions of a waterfall master so that we can
schedule tryjobs on those dimensions without relying on a handcrafted
configuration.

[Findit] Support 'use_swarmbucket' config for defaults.

This new setting will let us simplify the extensive configuration for
builder-to-trybot mapping, by using default
luci.chromium.try/findit_variable when set.

[Findit] Get trybot dimensions from swarmbucket api.

This change gets the trybot dimensions dynamically from buildbucket via
the swarmbucket api when the original failure happened on a luci bot.

Note that this does not yet make the tryjob necessarily happen on a
swarming trybot as this is still determined by the static mapping when
triggering the tryjob, but only gets the dimensions (which may be
ignored if the static mapping points to a buildbot trybot)

A later change will make the tryjobs be triggered on swarming if the
matching dimensions are available on Findit's swarming pool and the
static mapping doesn't force buildbot trybot.
