- Extracted shared ACL setup logic into a private helper method, setupAcl().
- Split original testCRUDAcl into two separate tests: testCRUDAclReadAll and testCRUDAclReadOne.
- Each test case now represents a unique scenario for better readability and maintainability.
- Replaced assertTrue(false) with fail() in catch blocks for better test failure indication.
These changes aim to enhance the clarity and maintainability of the test suite, and ensure each test case checks only one scenario.

The CloudStack coding conventions specify org.apache.commons.lang3.StringUtils as the default alternative for string operations, and com.cloud.utils.StringUtils for operations not covered by the former.
Since org.apache.commons.lang3.StringUtils is seen as the default alternative and is used more often in NetworkModelImpl.java, this PR inverts how these two classes are referenced in this file in order to standardize it.
OAuth2, the industry-standard authorization or authentication framework, simplifies the process of
granting access to resources. CloudStack supports OAuth2 authentication wherein users can login into
CloudStack without using a username and password. Support for Google and Github providers has been added.
Other OAuth2 providers can be easily integrated with CloudStack using its plugin framework.
The login page will show provider options when the OAuth2 is enabled and corresponding providers are configured.
"OAuth configuration" sub-section is present under "Configuration" where admins can register the corresponding
OAuth providers.
This pull request (PR) implements a Distributed Resource Scheduler (DRS) for a CloudStack cluster. The primary objective of this feature is to enable automatic resource optimization and workload balancing within the cluster by live migrating the VMs as per configuration.
Administrators can also execute DRS manually for a cluster, using the UI or the API.
Adds support for two algorithms - condensed & balanced. Algorithms are pluggable allowing ACS Administrators to have customized control over scheduling.
Implementation
There are three top level components:
Scheduler
A timer task which:
Generate DRS plan for clusters
Process DRS plan
Remove old DRS plan records
DRS Execution
We go through each VM in the cluster and use the specified algorithm to check if DRS is required and to calculate cost, benefit & improvement of migrating that VM to another host in the cluster. On the basis of cost, benefit & improvement, the best migration is selected for the current iteration and the VM is migrated. The maximum number of iterations (live migrations) possible on the cluster is defined by drs.iterations which is defined as a percentage (as a value between 0 and 1) of total number of workloads.
Algorithm
Every algorithms implements two methods:
needsDrs - to check if drs is required for cluster
getMetrics - to calculate cost, benefit & improvement of a migrating a VM to another host.
Algorithms
Condensed - Packs all the VMs on minimum number of hosts in the cluster.
Balanced - Distributes the VMs evenly across hosts in the cluster.
Algorithms use drs.level to decide the amount of imbalance to allow in the cluster.
APIs Added
listClusterDrsPlan
id - ID of the DRS plan to list
clusterid - to list plans for a cluster id
generateClusterDrsPlan
id - cluster id
iterations - The maximum number of iterations in a DRS job defined as a percentage (as a value between 0 and 1) of total number of workloads. Defaults to value of cluster's drs.iterations setting.
executeClusterDrsPlan
id - ID of the cluster for which DRS plan is to be executed.
migrateto - This parameter specifies the mapping between a vm and a host to migrate that VM. Format of this parameter: migrateto[vm-index].vm=<uuid>&migrateto[vm-index].host=<uuid>.
Config Keys Added
ClusterDrsPlanExpireInterval
Key drs.plan.expire.interval
Scope Global
Default Value 30 days
Description The interval in days after which old DRS records will be cleaned up.
ClusterDrsEnabled
Key drs.automatic.enable
Scope Cluster
Default Value false
Description Enable/disable automatic DRS on a cluster.
ClusterDrsInterval
Key drs.automatic.interval
Scope Cluster
Default Value 60 minutes
Description The interval in minutes after which a periodic background thread will schedule DRS for a cluster.
ClusterDrsIterations
Key drs.max.migrations
Scope Cluster
Default Value 50
Description Maximum number of live migrations in a DRS execution.
ClusterDrsAlgorithm
Key drs.algorithm
Scope Cluster
Default Value condensed
Description DRS algorithm to execute on the cluster. This PR implements two algorithms - balanced & condensed.
ClusterDrsLevel
Key drs.imbalance
Scope Cluster
Default Value 0.5
Description Percentage (as a value between 0.0 and 1.0) of imbalance allowed in the cluster. 1.0 means no imbalance
is allowed and 0.0 means imbalance is allowed.
ClusterDrsMetric
Key drs.imbalance.metric
Scope Cluster
Default Value memory
Description The cluster imbalance metric to use when checking the drs.imbalance.threshold. Possible values are memory and cpu.
Maximum 10 collaborators are supported by ASF infra.

This improves the function to not show the alert status on host icon
when there are no hosts in alert state. Instead a colour/theme matching
exclaimation is show next to the host icon, otherwise show green tick.

This PR adds new functionality to copy snapshots across zones and take snapshots for multiple zones.
Copy functionality is similar to template copy. The source zone acts as the web server from where the destination zone(s) can download the snapshot files. For this purpose, a new API - `copySnapshot` has been added. The response for copySnapshot will be returning zone and download details from the first destination zone of the request. This behaviour is similar to the `copyTemplate` API.
In a similar manner, multiple zones can be selected while taking the snapshots or creating snapshot policies. For this snapshot will be taken in the base zone(in which volume is present) and then copied to the additional zones. A new parameter - `zoneids` has been added to `createSnapshot` and `createSnapshotPolicy` APIs.
As snapshots can be present on multiple zones (secondary stores), a new parameter `zoneid` has been added to delete the snapshot copy on a specific zone.
`listSnapshots` API has been updated to allow listing snapshot entries for different zones/datastores. New parameters - `showUnique`, `locationType` have been added.
Events generated during snapshot operations will now be linked to the snapshot itself rather than the volume of the snapshot.
`listSnapshotPolicies` and `createSnapshotPolicy` APIs will return zone details of the zones in which backup will be scheduled for the policy.

Making a diskful resource was meant as an optimization,
but cannot work on non hyperconverged setups,
as the storage nodes (diskful) are not part of the cloudstack cluster.
Fixes#8034
Adds the following test for a backed-up snapshot (original template and VM deleted beforehand):
- Create volume from snapshot
- Create a template from the snapshot and deploy a VM using it
