Getting ready for async runner
Fixed GUI Runs > RunHistoryView bug

Moved read-only marking part to extract-output
BuildKit update
Initial version of ssh-cluster runner

that executes runs on a set of remote hosts asynchronously.  3x-sync should
be periodically used to fetch the results into the local repository.
Implemented with a base.async runner which serves as a base for runners that
schedule runs asynchronously and poll/synchronize periodically.
