Enable the managed-storage template cache flow for the ONTAP primary storage plugin so that VM root volumes are cloned from a template copy kept on the pool's FlexVolume instead of being copied from secondary storage for every deployment. - Advertise CAN_CREATE_VOLUME_FROM_VOLUME from the datastore driver. - Create the template cache on primary: an iSCSI LUN (identity tracked on template_spool_ref) or a qcow2 file for NFS, populated by the KVM host. - Clone new volumes from the cached template: LUN clone for iSCSI and ONTAP file clone (FileCloneRequest) for NFS, growing the clone when the disk offering is larger than the template. - Clean up the cached LUN/file when the template is removed from the pool; a missing file is treated as already deleted. - Move protocol-specific create/clone/resize logic into UnifiedSANStrategy and UnifiedNASStrategy, and add a StorageStrategy helper to poll an optional async job. - Add unit tests for the driver and the NAS/SAN strategies. ### Description This PR... <!--- Describe your changes in DETAIL - And how has behaviour functionally changed. --> <!-- For new features, provide link to FS, dev ML discussion etc. --> <!-- In case of bug fix, the expected and actual behaviours, steps to reproduce. --> <!-- When "Fixes: #<id>" is specified, the issue/PR will automatically be closed when this PR gets merged --> <!-- For addressing multiple issues/PRs, use multiple "Fixes: #<id>" --> <!-- Fixes: # --> <!--- ******************************************************************************* --> <!--- NOTE: AUTOMATION USES THE DESCRIPTIONS TO SET LABELS AND PRODUCE DOCUMENTATION. --> <!--- PLEASE PUT AN 'X' in only **ONE** box --> <!--- ******************************************************************************* --> ### Types of changes - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] New feature (non-breaking change which adds functionality) - [ ] Bug fix (non-breaking change which fixes an issue) - [ ] Enhancement (improves an existing feature and functionality) - [ ] Cleanup (Code refactoring and cleanup, that may add test cases) - [ ] Build/CI - [ ] Test (unit or integration test code) ### Feature/Enhancement Scale or Bug Severity #### Feature/Enhancement Scale - [ ] Major - [ ] Minor #### Bug Severity - [ ] BLOCKER - [ ] Critical - [ ] Major - [ ] Minor - [ ] Trivial ### Screenshots (if appropriate): ### How Has This Been Tested? <!-- Please describe in detail how you tested your changes. --> <!-- Include details of your testing environment, and the tests you ran to --> #### How did you try to break this feature and the system with this change? <!-- see how your change affects other areas of the code, etc. --> <!-- Please read the [CONTRIBUTING](https://github.com/apache/cloudstack/blob/main/CONTRIBUTING.md) document --> -- This is an automated message from the Apache Git Service.
