Extending the current functionality of KVM Host HA for the StorPool storage plugin and the option for easy integration for the rest of the storage plugins to support Host HA
This extension works like the current NFS storage implementation. It allows it to be used simultaneously with NFS and StorPool storage or only with StorPool primary storage.
If it is used with different primary storages like NFS and StorPool, and one of the health checks fails for storage, there is an option to report the failure to the management with the global config kvm.ha.fence.on.storage.heartbeat.failure. By default this option is disabled when enabled the Host HA service will continue with the checks on the host and eventually will fence the host
This PR aligns the use of terminology, renaming VM / virtual machine references to 'Instance' and also capitalising the terms Templates, Network, Snapshot, User, Account in CloudStack UI. “VM snapshots” moved under the “Compute” main menu, and renamed to “Instance Snapshots”. “Snapshots” (under Storage section) renamed to “Volume Snapshots”.
- 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.
