Allow optionally to disable range caching. (#9908)
The default behavior is to cache each range requested
to cache drive. Add an environment variable
`MINIO_RANGE_CACHE` - when set to off, it disables
range caching and instead downloads entire object
in the background.

Fixes #9870

Add cache eviction low and high watermarks (#8958)
To allow better control the cache eviction process.

Introduce MINIO_CACHE_WATERMARK_LOW and 
MINIO_CACHE_WATERMARK_HIGH env. variables to specify 
when to stop/start cache eviction process. 

Deprecate MINIO_CACHE_EXPIRY environment variable. Cache 
gc sweeps at 30 minute intervals whenever high watermark is
reached to clear least recently accessed entries in the cache
until sufficient space is cleared to reach the low watermark.

Garbage collection uses an adaptive file scoring approach based
on last access time, with greater weights assigned to larger
objects and those with more hits to find the candidates for eviction.

Thanks to @klauspost for this file scoring algorithm

poornas 76df027264 Allow caching only in gateway mode. (#8232)
This PR changes cache on PUT behavior to background fill the cache
after PutObject completes. This will avoid concurrency issues as in #8219.

Added cleanup of partially filled cache to prevent cache corruption
- Fixes #8208

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.
