poornas 9199033db7 Set X-Cache and X-Cache-Lookup headers for cache (#8794)
X-Cache sets cache status of HIT if object is
served from the disk cache, or MISS otherwise.
X-Cache-Lookup is set to HIT if object was found
in the cache even if not served (for e.g. if cache
 entry was invalidated by ETag verification)

Harshavardhana ff5bf51952 admin/heal: Fix deep healing to heal objects under more conditions (#8321)
- Heal if the part.1 is truncated from its original size
- Heal if the part.1 fails while being verified in between
- Heal if the part.1 fails while being at a certain offset

Other cleanups include make sure to flush the HTTP responses
properly from storage-rest-server, avoid using 'defer' to
improve call latency. 'defer' incurs latency avoid them
in our hot-paths such as storage-rest handlers.

poornas 3385bf3da8 Rewrite cache implementation to cache only on GET (#7694)
Fixes #7458
Fixes #7573 
Fixes #7938 
Fixes #6934
Fixes #6265 
Fixes #6630 

This will allow the cache to consistently work for
server and gateways. Range GET requests will
be cached in the background after the request
is served from the backend.

- All cached content is automatically bitrot protected.

- Avoid ETag verification if a cache-control header
is set and the cached content is still valid.

- This PR changes the cache backend format, and all existing
content will be migrated to the new format. Until the data is
migrated completely, all content will be served from the backend.
