Jim Gauld afbc586f86 systemd DropIn to disable software CPUShares on systemcontroller 
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

README.rst

stx-puppet

The starlingx/stx-puppet repository handles the Puppet service1.

The Puppet service runs during bootstrap, and at every reboot, to provide a consistent configuration across the StarlingX system nodes.

This repository is not intended to be developed standalone, but rather as part of the StarlingX Source System, which is defined by the StarlingX manifest2.
