- Revert "Remove links in openstack/charts/"
This reverts commit 24e98899d2066a72abaa08e1fb082e335311db2b.
Reason for revert: Seems to have broken lint in a subsequent
change in this repository, revert to fix gate.

- Merge "Optimize numa_fit_instance_to_host"
- Optimize numa_fit_instance_to_host
The numa_fit_instance_to_host algorithm tries all the possible
host cell permutations to fit the instance cells. So in worst case
scenario it does n! / (n-k)! _numa_fit_instance_cell calls
(n=len(host_cells) k=len(instance_cells)) to find if the instance can be
fit to the host. With 16 NUMA nodes host and 8 NUMA node guests this
means 500 million calls to _numa_fit_instance_cell. This takes excessive
time.
However going through these permutations there are many repetitive
host_cell, instance_cell pairs to try to fit.
E.g.
host_cells=[H1, H2, H2]
instance_cells=[G1, G2]
Produces pairings:
* H1 <- G1 and H2 <- G2
* H1 <- G1 and H3 <- G2
...
Here G1 is checked to fit H1 twice. But if it does not fit in the first
time then we know that it will not fit in the second time either. So we
can cache the result of the first check and use that cache for the later
permutations.
This patch adds two caches to the algo. A fit_cache to hold
host_cell.id, instance_cell.id pairs that we know fit, and a
no_fit_cache for those pairs that we already know that doesn't fit.
This change significantly boost the performance of the algorithm. The
reproduction provided in the bug 1978372 took 6 minutes on my local
machine to run without the optimization. With the optimization it run in
3 seconds.
This change increase the memory usage of the algorithm with the two
caches. Those caches are sets of integer two tuples. And the total size
of the cache is the total number of possible host_cell, instance_cell
pairs which is len(host_cell) * len(instance_cells). So form the above
example (16 host, 8 instance NUMA) it is 128 pairs of integers in the
cache. That will not cause a significant memory increase.
Closes-Bug: #1978372

- Support image registries with authentication
Based on spec
support-OCI-image-registry-with-authentication-turned-on.rst
Each Helm chart can configure an OCI image registry and
credentials to use. A Kubernetes secret is then created with this
info. Service Accounts then specify an imagePullSecret specifying
the Secret with creds for the registry. Then any pod using one
of these ServiceAccounts may pull images from an authenticated
container registry.

- Merge "manager: Reduce unnecessary calls"
- manager: Reduce unnecessary calls
The call to get_volume_connector() is unnecessary when all
BDMs are not volume. It affects the performance of live
migration or shutdown when instance hasn't attached volumes.
Set the connector is none and call 'get_volume_connector'
to assign a value to connector when it is first used.

- Merge "PowerMax Driver - Check for moving to same target"
- PowerMax Driver - Check for moving to same target
On a move operation check that the target storage group is
not the same as the source storage group which would make the
move unnecessary.
