### Description This PR adds support to enable/disable VM High Availability manager. - New config 'vm.ha.enabled' with Zone scope is added, to enable/disable VM High Availability manager. This is enable by default (for backward compatibilty). When enabled, the VM HA WorkItems (for VM Stop, Restart, Migration, Destroy) can be created and the scheduled items are executed. When disabled, new VM HA WorkItems are not allowed and the scheduled items are retried until max retries configured at 'vm.ha.migration.max.retries' (executed in case HA is re-enabled during retry attempts), and then purged after 'time.between.failures' by the cleanup thread that runs regularly at 'time.between.cleanup'. - New config 'vm.ha.alerts.enabled' with Zone scope is added, to enable/disable alerts for the VM HA operations. This is enabled by default. <!--- 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) - [x] 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 - [x] Major - [ ] Minor #### Bug Severity - [ ] BLOCKER - [ ] Critical - [ ] Major - [ ] Minor - [ ] Trivial ### Screenshots (if appropriate): ### How Has This Been Tested?
