Each metadata ops have a list of errors which can be
ignored, this is essentially needed when
- disks are not found
- disks are found but cannot be accessed (permission denied)
- disks are there but fresh disks were added
This is needed since we don't have healing code in place where
it would have healed the fresh disks added.
Fixes#2072
Previously xl.isObject() returns false if one of the disk doesn't have
the object. Its possible that object may be present in another disk.
This patch fixes the issue by returning false only if given prefix
doesn't exist in all disks.
Fixes#1855
Remove usage of getFileVersionQuorumMap, instead use listFileVersions
to get the version list and extract higherVersion.
