Peter Waller 671c12204c Implement build cancellation ... Add the capability to cancel the build by disconnecting the client. This adds a `cancelled` channel which is used to signal that a build should halt. The build is halted by sending a Kill signal and noticing that the cancellation channel is closed. This first pass implementation does not allow cancellation during a pull, but that will come in a subsequent PR. * Add documentation of cancellation to cli and API * Protect job cancellation with sync.Once * Add TestBuildCancelationKillsSleep * Add test case for build cancellation of RUN statements.
