Allow preserving duplicate MACs during VM import

[andrijapanicsb]

Description

This change adds an explicit import option to preserve duplicate NIC MAC addresses during VM import workflows.

The existing forced option continues to mean: if the imported VM has a NIC MAC address that already exists on the selected CloudStack network, continue the import by generating a new MAC address.

A new allowduplicatemacaddresses API parameter allows the opposite behavior: preserve the imported VM's MAC address even if that same MAC is already present on the selected network. The two options are mutually exclusive.

This is useful for migration cutover workflows where a VMware-sourced VM is imported to KVM while the original VM still exists in CloudStack, but the operator wants the imported instance to keep the same MAC address for guest/network continuity.

The UI import form now labels forced as "Generate new MAC if required" and exposes a separate "Allow duplicate MAC addresses" switch.
These MAC conflict)ing) options are shown for VM migration/import flows where an existing source VM has NICs to preserve.
They are hidden when creating a brand-new VM from existing QCOW2 files on local/shared storage, because that path creates a new CloudStack NIC instead of importing a source NIC from another VM.

In other words, the MAC options are available when CloudStack has to decide what to do with a MAC address from a source VM: either keep it, generate a replacement, or fail on conflict. They are not shown for QCOW2 disk import, where there is no source VM NIC to preserve.

[blueorangutan]

@andrijapanicsb a [SL] Jenkins job has been kicked to build packages. It will be bundled with no SystemVM templates. I'll keep you posted as I make progress.

@andrijapanicsb [SL] I understand these words: "help", "hello", "thanks", "package", "test"
Test command usage: test [mgmt os] [hypervisor] [keepEnv] [qemuEv] [basicZone|securityGroups]
Mgmt OS options: ['suse15', 'alma10', 'ol10', 'rocky10', 'alma9', 'centos7', 'centos6', 'rocky9', 'alma8', 'ubuntu18', 'ol9', 'ol8', 'ubuntu22', 'debian12', 'ubuntu20', 'rocky8', 'ubuntu24']
Hypervisor options: ['kvm-centos6', 'kvm-centos7', 'kvm-rocky8', 'kvm-rocky9', 'kvm-rocky10', 'kvm-ol8', 'kvm-ol9', 'kvm-ol10', 'kvm-alma8', 'kvm-alma9', 'kvm-alma10', 'kvm-ubuntu18', 'kvm-ubuntu20', 'kvm-ubuntu22', 'kvm-ubuntu24', 'kvm-debian12', 'kvm-suse15', 'vmware-55u3', 'vmware-60u2', 'vmware-65u2', 'vmware-67u3', 'vmware-70u1', 'vmware-70u2', 'vmware-70u3', 'vmware-80', 'vmware-80u1', 'vmware-80u2', 'vmware-80u3', 'vmware-80u3e', 'xenserver-65sp1', 'xenserver-71', 'xenserver-74', 'xenserver-84', 'xcpng74', 'xcpng76', 'xcpng80', 'xcpng81', 'xcpng82', 'xcpng83']
Note: when keepEnv is passed, you need to specify mgmt server os and hypervisor or use the matrix command.
when qemuEv is passed, it will deploy KVM hyperviosr hosts with qemu-kvm-ev, else it will default to stock qemu.
When basicZone and/or securityGroups are passed it will create a zone of the last type specified (default is Advanced)
Package command usage: package [all(default value),kvm,xen,vmware,hyperv,ovm] - a comma separated list can be passed with package command to bundle the required hypervisor's systemVM templates. Not passing any argument will bundle all - kvm,xen and vmware templates.
