add '.healing.bin' for tracking currently healing disk (#10573)
add a hint on the disk to allow for tracking fresh disk
being healed, to allow for restartable heals, and also
use this as a way to track and remove disks.

There are more pending changes where we should move
all the disk formatting logic to backend drives, this
PR doesn't deal with this refactor instead makes it
easier to track healing in the future.

Add storage layer contexts (#10321)
Add context to all (non-trivial) calls to the storage layer. 

Contexts are propagated through the REST client.

- `context.TODO()` is left in place for the places where it needs to be added to the caller.
- `endWalkCh` could probably be removed from the walkers, but no changes so far.

The "dangerous" part is that now a caller disconnecting *will* propagate down,  so a 
"delete" operation will now be interrupted. In some cases we might want to disconnect 
this functionality so the operation completes if it has started, leaving the system in a cleaner state.

tolerate listing with only readQuorum disks (#10357)
We can reduce this further in the future, but this is a good
value to keep around. With the advent of continuous healing,
we can be assured that namespace will eventually be
consistent so we are okay to avoid the necessity to
a list across all drives on all sets.

Bonus Pop()'s in parallel seem to have the potential to
wait too on large drive setups and cause more slowness
instead of gaining any performance remove it for now.

Also, implement load balanced reply for local disks,
ensuring that local disks have an affinity for

handle fresh setup with mixed drives (#10273)
fresh drive setups when one of the drive is
a root drive, we should ignore such a root
drive and not proceed to format.

This PR handles this properly by marking
the disks which are root disk and they are
taken offline.

fix: heal replaced drives properly (#10069)
healing was not working properly when drives were
replaced, due to the error check in root disk
calculation this PR fixes this behavior

This PR also adds additional fix for missing
metadata entries from .minio.sys as part of
disk healing as well.

Added code to ignore and print more context
sensitive errors for better debugging.

This PR is continuation of fix in 7b14e9b660

Support bucket versioning (#9377)
- Implement a new xl.json 2.0.0 format to support,
  this moves the entire marshaling logic to POSIX
  layer, top layer always consumes a common FileInfo
  construct which simplifies the metadata reads.
- Implement list object versions
- Migrate to siphash from crchash for new deployments
  for object placements.

Fixes #2111
