### problem
Importing a volume using ImportVolumeCmd into a KVM cluster with
SharedMountPoint primary storage fails with:
_Importing and unmanaging volume are not supported for pool type
SharedMountPoint on hypervisor KVM_
This failure is triggered by an explicit validation in
_VolumeImportUnmanageManagerImpl.checkIfHostAndPoolSupported._
While documentation specifies NFS-only support for importVM,
SharedMountPoint is also a filesystem-based shared storage type. Its exclusion
seems unnecessary and may indicate a gap. Allowing SharedMountPoint or
clarifying the rationale for this restriction would help improve consistency.
Note: SharedMountPoint is filesystem-based shared storage similar to NFS and
is accessible across hosts. Since importVolume operates on disk files, its
exclusion appears unnecessary and inconsistent.
Below is the error we see in the logs

### versions
CloudStack version: 4.x (please replace with your exact version)
Hypervisor: KVM
Primary storage: SharedMountPoint (clustered filesystem mounted on all hosts)
### The steps to reproduce the bug
1. Configure a KVM cluster with SharedMountPoint primary storage
2. Ensure storage is mounted on all hosts at the same path
3. Attempt to import a volume (e.g., QCOW2 disk) using ImportVolumeCmd
4. Observe failure with "not supported for pool type SharedMountPoint"
### What to do about it?
ImportVolumeCmd currently supports NFS, Ceph, and Local primary storage on
KVM. SharedMountPoint is also a valid shared filesystem-based primary storage
type on KVM and should be treated consistently.
Validation logic should include:
**NetworkFilesystem (NFS)
RBD (Ceph)
Filesystem (Local storage)
SharedMountPoint**
instead of explicitly rejecting SharedMountPoint.
