This PR enhances the existing CLVM implementation which was based on the deprecated CLVM technology which was based on corosync/pacemaker. With RHEL 7 having reached EOL, CLVM seems to be broken. CLVM supports RAW volumes on LVM , where as CLVM_NG support QCOW2 on LVM.
Further details: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Modernized+CLVM%3A+Enhancements+and+CLVM_NG+support
NOTE: On testing - it was identified that incremental snapshots for clvm-ng do not work as expected. As of now it's been removed from scope. So, CLVM and CLVM_NG would only support full snapshots.

* add support to revert snapshot for clvm
* make zero fill configurable
* make setting non-dynamic & fix test
* fix locking at vol/vm creation
* fix revert snapshot format type and handle revert snapshot functionality for clvm
* 1. Create clvmlockmanager and move common code \n
2. handle attaching volumes to stopped VMs \n
3. Handle lock transfer when VM is started on another host
* add license
* remove command/answer classes from sonar coverage check
* add support for new gen clvm with template (qcow2) backing
* Add support for clvm_ng - which allows qcow2 on block storage , linked clones, etc
* fix test and use physical size + 50% of virtual size for backing file, while virtual size + pe for disk
* migrate clvm volumes as full clone and allow migration from clvm to nfs
* fix clvm_ng to nfs migration, and handle overhead calc
* support live migration from clvm_ng to nfs and vice-versa
* add support to migrate to and from clvm to nfs
* fix creation of volume on destination host during migration to clvm/clvm-ng
* support live vm migration between clvm -> clvm-ng (vice-versa), nfs -> clvm (vice-versa) and nfs->clvm-ng (vice-versa)
* add unit tests for clvm/clvm_ng operations
* Add support for incremental volume snapshots for clvm_ng
* prevent snapshot backup for incremental clvm_ng snaps, fix build failure, add unit tests
* fix lockhost on creation of volumes from snap and fix bitmap issue when migrating a vol with incremental snap
* restrict pre and post migration commands to only kvm hosts where vm has CLVM/CLVM-NG volumes
* evist lock tracking - use lvs command to get lock host than DB
* add test for pre/post migration
* Create a CLVM storage adaptor
* update existing clvm get stats method
* fix precommit check failure
* Apply suggestions from code review

* improve lock host retrieval logic and quicker retrival using db host as first check point and then fanning out
* add proper support for resizing of clvm_ng which calculated PE correctly for qcow2 metadata
* fallback to full snapshots for clvm-ng - incremental not supported in 4.23
* expunge volume detail of lock host on vm expunge
* if vmmigration with volume is done to the same clvm volume group, then dont do data transfer, just lock transfer and vm
* add clvm pools with deterministic uuid , so as to prevent adding the same pool twic
* added a small improvement to factor in a senario when lv is inactive on all hosts, could happen in storage outage issue
* address comment - extract common code for endpoint identification if clvm pool type
* Address comments - add early return guard to reduce indentation
* minor improvement - when migrating vm with volumes, if there's a failures, change the clvm vols to exclusive on source from shared, and on success, change dest vol to exclusive only for cross-pool migration
* cleanup unused code and tests for incremental snaps for clvmng and other cleanups
* allow storage browser to list lv in clvm, fix clvm shrink, overprovisioning factor isnt used for clvm pools - so set it to 1 and prevented display of provisioning type for clvm
* no need to have locktransfercommand to execute in sequence
* increase lv cmd timeouts to consider cluster load

Fix snapshot physical size after migration (#12166)
ConfigDrive: use file absolute path instead of canonical path to create ISO (#11623)

Fix: proper permissions for systemvm template registrations on hardened systems (#12098)
Allow modification of user vm details if user.vm.readonly.details is empty (#10456)
NPE fix while deleting storage pool when pool has detached volumes (#12451)
This fixes the case when the storage pool is removed as well the KVM
host and the subsequent volumes on the host. When that happened, listing
snapshots (for recovery purposes) cause NPE as the pool_id was null, but
last_pool_id for the related destroyed volume wasn't null. This adds a
fallback logic.

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 APIs, error and log messages, events, tooltips, etc. Many typos, grammar and spelling mistakes were fixed, also terms like IPv4, VPN, VPC, etc. were properly capitalised. Some error messages were cleaned for better readability. The test cases, expecting some exception strings were adjusted accordingly.
Here is the wiki page, describing the changes in details:

* Migrate volume improvements, to bypass secondary storage when copy volume between pools is allowed directly
* Bypass secondary storage for copy volume between zone-wide pools and
- local storage on host in the same zone
- cluser-wide pools in the same zone
* Bypass secondary storage for volumes on ceph/rdb pool when the scope permits
* Fix dest disk format while migrating volume from ceph/rbd to nfs, and some code improvements
* unit tests
* Update suitable disk offering(s) for volume(s) after migrate VM with volumes when change in pool type (shared or local)
Currently, Migrate VM with volume(s) bypasses the service and disk offerings of the volumes, as the target pools for migration are specified,
which ignores the offerings. Offering change is required when pool type (shared or local) is changed, mainly
- when volume on shared pool is migrated to local pool
- when volume on local pool is migrated to shared pool
* Update with proper message while migrate volume when target pool and offering type mismatches (both are not shared/local)
* Consider host scope first during endpoint selection while copying between primary storages
* Update disk offering count (for listDiskOfferings api) while removing offerings with tags mismatch with storage tags
* Remove allocated snapshots / vm snapshots on start
* Check and Cleanup snapshots / vm snapshots on MS start
* rebase fixes
* Update volume state (from Snapshotting) on MS start when its snapshot job not finished and snapshot in Creating state
When removing an incremental snapshot (For both KVM and XenServer), it is checked if the snapshot has a child or not. If it has, then the snapshot is not removed from the storage.
For KVM incremental snapshots, snapshots in the same chain may be on different secondary storages (within the same zone).
However, the child search process only considers snapshots from the same secondary storage as theirs. Therefore, if a snapshot has its parent snapshot on a different secondary storage, it will be completely removed, making the snapshot chain inconsistent.
