Based on DC scale batch subcloud prestage operations, it was observed
80 cores fully utilized zero idle, causing starvation of software API.
The software-controller-daemon process was spreading work over multiple
seconds. Any processes used for DC operations are payload and should
fight for CPU equally.
This updates the list of systemd services that require disabled
CPUShares instead of having the reduced value 128 on all other nodes.
This adds: software-controller-daemon, software, and
sw-patch-controller-daemon.
Partial-Bug: 2092319
TEST PLAN:
- PASS: Fresh install DC lab
- PASS: Verify systemcontroller DropIn files are created with
CPUShares=1024 for: software-controller-daemon, software,
sw-patch-controller-daemon
