Since bug-1790's fix (9caf1424) counts a job's full task total against
global limits, the repo's limit1 (all users except rshen share 3 slots)
pends xce_test's root-submitted 33-task job forever, so the multihost
e2e fixture failed even though the allocator is correct.
deploy-ha.sh gains an optional XCE_DEPLOY_CONFIG_DIR (default unchanged:
src/configs). run-multihost-verify.sh copies src/configs into its deploy
dir, replaces limits.yaml with an empty list, and deploys with that
override.
