needed to support them.

Can you also update the docs at https://www.chromium.org/chromium-os/build/using-remote-trybots ?

Running "cbuildbot" instead of "cros tryjob" out of habit just fails with "ERROR: A buildroot is required to build."

Sorry, I put in a friendlier warning, but much produce the errors in the wrong order.

cbuildbot: Tweak --local and --remote messages.

We recently removed --local and --remote tryjob support from
cbuildbot, but the messaging to help people who use the wrong tryjob
command didn't work out right. Fix it!

remote_try: Remove unused functionality.

This library originally worked by committing CLs to manifest-versions,
which triggered the trybot waterfall. Now that tryjobs can only be
triggered via buildbucket, there is no need to retain that
functionality.

Also, strip out support for a few other values that can't be specified
via cros tryjob.

remote_try: Remove more unused stuff.

Remove the tryjob format version concept, since it's not used (seems
like it hasn't been for a long time). Updated description of the
related cbuildbot argument --remote-version, but didn't remove that
since old tryjob clients will still send it.

Remove a couple of unused URL constants in remote_try.

Remove self.cache_key.

remote_try: Move from cbuildbot/ to lib/

Since this library no longer depends on any cbuildbot specific code,
it can now be considered a general library.
