Add support for better compression formats in zipdeploy API

[prvyk]

Current zipdeploy API uses ZIP archives which are far from optimal or modern compression. In particular, ZIP files compress files individually. Using a more modern format which allows for compressing multiple files together ('solid archiving' or 'deduping') allows for massive space/network traffic savings. For example, a webjob heavy deployment of mine could reduce artifact size from >220M to <9M if 7z is used instead of zip **.

This is in line with ecosystem support and recent developments:

• Azure Devops already supports compressing to 7zip:

• Windows 11 update adds support for other formats (like 7zip and rar) besides zip via libarchive.

** Comparing default Azure devops artefact to 7-zip compression with maximal settings. 7zip beats zip however on every setting. RAR maximal settings is about 8M too.
