feat: cache resources

[TrySound]

Ref #4077

How it works

• Cache-Control opts in caching (Cache-Control: max-age=3600)
• cached response is matched by url, method and body
• cache is invalidated with Cache-Control change
• responses stored with the cache are not replicated across regions
• responses are not shared between projects
