XL: listOnlineDisks should use modTime instead of version. ( #2166 )
...
This change is needed to make reading from objects future proof
in-terms of handling online disks. Our current counter is not
based on affirmative knowledge and relies on arithmetic sequence
which can lead to bugs.
Using modTime simplifies the understanding of `xl.json` and future
tooling / debugging of the format.

XL: Implement ignore errors. ( #2136 )
...
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.

AppendFile ensures that it appends the entire buffer. Returns
an error otherwise, this patch removes the necessity for the
