Introduce Kusto management commands

[jessejlt]

Create a new CRD, ManagementCommands, that enable maintaining Kusto clusters via execution of arbitrary managemet commands.

This pull request introduces significant changes to the api/v1, ingestor/adx, and ingestor/storage directories to support the management of commands in the system. The key changes include the addition of new types and methods for handling management commands, updates to deepcopy functions, and modifications to tests to accommodate these new functionalities.

New Features:

• Management Commands API:
  • Added ManagementCommand and ManagementCommandList types, along with their specifications and statuses in api/v1/managementcommand_types.go.
  • Introduced ManagementCommandTask and its related methods to handle the execution and status updates of management commands in ingestor/adx/tasks.go.

Codebase Enhancements:

• Deepcopy Functions:
  • Updated DeepCopyInto and DeepCopy methods for AlertRule, AlertRuleSpec, AlertRuleStatus, Function, FunctionList, ManagementCommand, and ManagementCommandList in api/v1/zz_generated.deepcopy.go. [1] [2] [3] [4] [5] [6]

Testing:

• Test Adjustments:
  • Modified existing tests and added new tests for the management commands in ingestor/adx/tasks_test.go and ingestor/storage/kql_functions_test.go. These changes include setting up the test environment, creating management command resources, and verifying their execution and status updates. [1] [2] [3] [4] [5] [6] [7] [8]

Bug Fixes:

• Error Handling:
  • Improved error handling by replacing fmt.Errorf with errors.New in ingestor/storage/kql_functions.go.

Miscellaneous:

• Code Cleanup:
  • Removed unused imports and redundant code in various files to streamline the codebase. [1] [2] [3] [4] [5] [6]

These changes collectively enhance the functionality and maintainability of the codebase, particularly in managing and executing commands within the system.
