[Workbench] A cancelled container request page should show the "Re-run" button
Right now the Re-run button appears when a given container request's state is 'Final'.
Cancelled CRs (
state 'Committed' && priority 0) should either show the Re-run button, allowing the user to choose if it should reuse containers, or should have a "resume" or "restart" option which sets
priority: 1 allowing the container to execute again.
Add relevant tests.
