Timur Kumakbayev f9f8eed94b Active Cluster Support, Pod Quota Fixes,Token Cache and CI Improvements (#81)
feat: add Active Cluster support and improve plugin stability

## Major Features

### Active Cluster Support (Experimental) (#42)
- Add support for multiple PureStorage arrays in Active Cluster configuration
- Automatic volume connection on all arrays for high availability
- Configure via comma-separated addresses and tokens

### Pod Quota Limit Support (#69)
- Add proper handling of pod quota_limit parameter
- Use quota_limit when set, fall back to array capacity when unlimited
- Fix capacity reporting for pods with quotas

### Session Token Caching
- Implement session token caching in /etc/pve/priv/purestorage/
- Automatic token refresh at 80% of TTL to prevent expiration
- In-memory and file-based caching with jitter to prevent thundering herd

### Debug Logging
- Add configurable debug logging with 4 levels (0-3)
- Support both config parameter and PURESTORAGE_DEBUG environment variable

## Bug Fixes
- Fix volume deletion when connected to multiple hosts
- Query all connections before destroy
- Disconnect from all hosts on all arrays
- Prevents "Cannot destroy volume because it is currently connected" error

## CI/CD Improvements
- Add workflow_dispatch trigger to checks workflow
- Add option to check all files or only changed files
- Add comprehensive markdown linting with markdownlint-cli2

## Testing
- Add token caching tests (tests/token_cache_test.pl)
- Test token validation, expiration, and race conditions
- Test cleanup of expired cache files

## Refactoring (#72)
- Refactor volume removal logic to handle multiple host connections
- Improve device cleanup sequence (LVM, partitions, multipath)
- Extract connection querying logic before volume destruction
- Refactor CI/CD workflows for better maintainability and flexibility
- Improve error handling and logging throughout the plugin
- Enhance Active Cluster support with proper multi-array operations

## Code Formatting
- Format all Perl files with perltidy using .perltidyrc configuration
- Ensure consistent code style across the codebase
- Fix formatting issues in PureStoragePlugin.pm and test files

## Documentation
- Update README with new functionality
