There are a lot of test failures due to test_vm_life_cycle.py in multiple PRs due to host not available for migration of VMs.

While debugging I noticed that the hosts get stuck in Connecting state because MS is waiting for a response of the ReadyCommand from the agent. Since we take a lock on connection and disconnection, restarting the agent doesn't work. To fix this, we have to restart the MS or wait for ~1 hour (default timeout).
On the agent side, it gets stuck waiting for a response from the Script execution.
To reproduce, run smoke/test_vm_life_cycle.py (TestSecuredVmMigration test class to be specific). Once the tests are complete, you will notice that some hosts are stuck in Connecting state. And restarting the agent fails due to the named lock. Locks on DB can be checked using the below query.
SELECT *
FROM performance_schema.metadata_locks
INNER JOIN performance_schema.threads ON THREAD_ID = OWNER_THREAD_ID
WHERE PROCESSLIST_ID <> CONNECTION_ID() \G;
This PR adds a wait for the ready command and a timeout to the Script execution to ensure that the thread doesn't get stuck and the named lock from database is released.

This PR fixes reorder/list pools when cluster details are not set, while deploying vm / attaching volume.
Problem:
Attach volume to a VM fails, on infra with zone-wide pools & vm.allocation.algorithm=userdispersing as the cluster details are not set (passed as null) while reordering / listing pools by volumes.
Solution:
Ignore cluster details when not set, while reordering / listing pools by volumes.
This PR makes changes to use cluster's free metrics instead of used while computing imbalance for the cluster. This allows DRS to run for clusters where hosts doesn't have the same amount of metrics.
Currently, if a host is on alert, the option to reconnect it is not presented in the UI.

CloudStack can support max user data content to 1048576 bytes (the size can be configurable through vm.userdata.max.length setting, max 1048576), but it's limited due to the default Jetty max content size, which is 200000 bytes.

During management server initialization, some EmptyStackException and BeansException exceptions are always thrown; These exceptions do not affect ACS, however, they can cause confusion when observing the management server startup logs with DEBUG level on. The causes of the exceptions have been addressed.

This PR changes the password.policy.regex default value to empty. With an empty value for the configuration, it is skipped during the password policy check, only when the configuration is set to something different than a blank string, the regex will get checked.
This way, when creating a user on org.apache.cloudstack.ldap.LdapAuthenticator#authenticate() we won't get an error by default, as an empty value for the password is passed.
With this change, a fix is added for failures seen with test_08_migrate_vm or other migration-related tests because the target host is in `Connecting` state,

This PR updates the conserve mode of default vpc tier offering to conserve_mode=1
so we can create both port forwarding and load balancing rules on a public IP in vpc tiers.
This fixes#8313
When a public IP gets removed from quarantine, the removal reason gets saved to the database; however, it may also be useful for operators to know who removed the public IP from quarantine. For that reason, this PR extends the public IP quarantine feature so that the account that deliberately removed an IP from quarantine also gets saved to the database.
The Default View has a projects toggle button that allows users to see which resources belong to projects, but there is nothing to indicate which project they belong to.
For this reason, a project column was added if the projects button is enabled, indicating the name of the project to which the resource belongs.

1. Problem description
In Apache CloudStack (ACS), when a VM is deployed in a host with the KVM hypervisor, an XML file is created in the assigned host, which has a property shares that defines the weight of the VM to access the host CPU. The value of this property has no unit, and it is a relative measure to calculate how much CPU a given VM will have in the host. However, this value has a limit, which depends on the version of cgroup utilized by the host's kernel. The problem lies at the range value of shares that varies between both versions: [2, 264144] for cgroups version 1; and [1, 10000] for cgroups version 2. Currently, ACS calculates the value of shares using Equation 1, presented below, where CPU is the number of cores and speed is the CPU frequency; both specified in the VM's compute offering. Therefore, if a compute offering has, for example, 6 cores at 2 GHz, the shares value will be 12000 and an exception will be thrown by libvirt if the host utilizes cgroup v2. The second version is becoming the default one in current Linux distributions; thus, it is necessary to address this limitation.
Equation 1
shares = CPU * speed
Fixes: #6744
2. Proposed changes
To address the problem described, we propose to apply a scale conversion considering the max shares of the host. Using the same formula currently utilized by ACS, it is possible to calculate the maximum shares of a VM for a given host. In other words, using the number of cores and the nominal speed of the host's CPU as the upper limit of shares allowed to a VM. Then, this value will be scaled to the allowed interval of [1, 10000] of cgroup v2 by using a linear scale conversion.
The VM shares would be calculated as Equation 2, presented below, where VM requested shares is the requested shares value calculated using Equation 1, cgroup upper limit is fixed with a value of 10000 (cgroups v2 upper limit), and host max shares is the maximum shares value of the host, calculated using Equation 1. Using Equation 2, the only case where a VM passes the cgroup v2 limit is when the user requests more resources than the host has, which is not possible with the current implementation of ACS.
Equation 2
shares = (VM requested shares * cgroup upper limit)/host max shares
To implement the proposal, the following APIs will be updated: deployVirtualMachine, migrateVirtualMachine and scaleVirtualMachine. When a VM is being deployed, a new verification will be added to find a suitable host. The max shares of each host will be calculated, and the VM calculated shares will be verified if it does not surpass the host's value. Likewise, the migration of VMs will have a similar new verification. Lastly, the scale of VMs will also have the same verification for the VM's host.
To determine the max shares of a given host, we will use the same equation currently used in ACS for calculating the shares of VMs, presented in Section 1. When Equation 1 is used to determine the maximum shares of a host, CPU is the number of cores of the host, and speed is the nominal CPU speed, i.e., considering the CPU's base frequency.
It is important to note that these changes are only for hosts with the KVM hypervisor using cgroup v2 for now.
