cros tryjob: Add --swarming option.

This is a preliminary version of --swarming. It works, but generates
an unrelated URL for locating the tryjob.

cros tryjob: Use GE build details link for swarming jobs.

The buildbot URL doesn't work for swarming tryjobs. The GE build
details page in staging will be able to look up builds by buildbucket
id very shortly, so use that for the build URL.

Add the link to the GE production page, along with a TODO to use it
after the new support hits production (next Wednesday).
