extensions: add sync, download functionalities

[shwstppr]

Description

This change introduces support for:

• synchronizing extension files across management servers in a clustered environment.
• download extension files as an archive (from a desired management server in a clustered environment). If needed (cases when MS is not directly accessible), download can be made to work via SSVM and secondary storage.

Key changes:

• Adds new syncExtension API to trigger synchronization for a selected extension.
• Implements util to create .tgz archive of the extension directory or selected files for sync.
• For sync, sends DownloadAndSyncExtensionFilesCommand to peer management servers. Handles archive download, staging, and extraction on the receiver side.
• Adds new downloadExtension API to allow downloading extension files as an archive.
• Implements util to create .zip archive of the extension directory for download.
• For forcing download via secondary storage, global configuration - extension.share.download.use.secondary.storage can be used and set to true.
• Generates signed share URL with HMAC signature and expiry.
• URL expiry and file cleanup can be controlled via global configuration - extension.share.link.validity.interval
• Adds Sync Extension and Download Extension actions in the UI Extensions view.
• Updates events, logging, and cleanup of temporary share files.
• Refactors all filesystem-related code to the extensions framework layer.
• Checksum for extensions is now calculated and compared for all files in the extension directory.
