v0.24.0

Large release - lots of fixes, with a side of new features thrown in to
spice it up. This is actually a re-attempt of the same release, due to
issues and noticing a critical bug, that have now been fixed.

Features:

- neonvm-controller: Make max concurrency configurable via CLI (#773)

- neonvm-controller: VM startup metrics (#774)

No breaking changes.

No protocol changes.

Fixes:

- neonvm-controller: Fix overwriting runner version (#753)
- neonvm-runner: Don't log i/o timeout (#768)
- neonvm: Use crictl to change container CPU, ditch cgroup (#738)
  - This is a BIG change! It's disabled by default, can be enabled with
    a neonvm-controller flag.

- agent: Fix unregistered metric lastSendDuration (#787)
- neonvm-controller: Don't retry update on conflict (#796)

Other changes:

- neonvm-runner: Skip QEMU powerdown if already exited (#526)
- plugin: Unify reserve and unreserve logic (#666)
- neonvm: Use container statuses, not pod phase, to trigger restart (#749)
- neonvm-controlller: Use --concurrency-limit=128 (#783)

Upgrade path from v0.23.x:

- No ordering requirements.

v0.23.2

Backport of #773 to allow configuring max neonvm-controller max
concurrency.

Now that we have neonvm-controller metrics, we discovered that a couple
regions were sometimes saturating the concurrency limit for extended
periods of time.

Refer to #773 for more details.

v0.23.1

Enables SSH access to VMs by default — see #766 and #726 for more.

v0.23.0

Substantial release with many bugfixes and quality-of-life improvements.
Notable inclusions: SSH support for VMs, opt-in higher log throughput,
tech debt resolution inside the scheduler.

Features:

- neonvm: Clock synchronization using kvm_ptp (#732)
- neonvm: Enable SSH access into the VMs (#726)
- neonvm-controller: Expose default set of metrics (#739)
- neonvm-controller: Custom reconciler metrics (#757)

No breaking changes (kind of; see "Protocol changes").

Protocol changes:

- agent,plugin: Refer to memory quantities in bytes, not memory slots (#653)
- agent: Send compute unit in requests to plugin (#744)

Fixes:

- neonvm-runner: Use the right file extension for ISO images (#735)
- agent: Add small random amount to plugin requset tick (#745)
- agent: Sleep for random delay before first metrics request (#746)
- neonvm-runner: Pass logs through virtio-serial (#724)

No other changes.

Upgrade path from v0.22.0:

- The neonvm deployment must be updated BEFORE making use of the new
  vm-builder version, else ssh access and clock synchronization will not
  work.
- The new `spec.enableSSH` field on VMs is ignored by previous versions
  of the scheduler and autoscaler-agents; no ordering requirement there.
- The scheduler MUST be updated before autoscaler-agents, due to the
  protocol changes between them.
