Feature Request: Finer grained rebuild command

[randymarsh77]

Current Behavior LPRB supports "rebuild this" to re-trigger all PR builds. One primary use case of the command is to respond to a transient failure in some build infrastructure.

Problem In many cases, transient failures in build infrastructure only affect one of the possibly many PR builds managed by LPRB. Re-triggering all builds over utilizes resources, and might result in slower time-to-successful-checks if the only check(s) need re-triggering are faster than the others.

Proposals

• Support additional matching on the comment body to filter the list of jobs being re-triggered. e.g.

  rebuild this
  My-Unfortunately-Flakey-PR

• Automatically detect which builds have failed, just rebuild those. Possibly with a different command. e.g.

  rebuild failed

Support additional matching on the comment body to filter the list of jobs being re-triggered

Suggestion: make it just a one-liner, i.e., rebuild JobName1[, JobName2[, JobName3]]

Example usage: rebuild MyJob-Win-PR, MyJob-Mac-PR
