features/shard: Introducing sharding translator
Based on the high-level design by Anand V. Avati which can be found @
https://gist.github.com/avati/af04f1030dcf52e16535#sharding-xlator-stripe-20
Still to-do:
* complete implementation of inode write fops - [f]truncate,
zerofill, fallocate, discard
* introduce transaction mechanism in inode write fops
* complete readv
* Handle open with O_TRUNC
* Handle unlinking of all shards during unlink/rename
* Compute total ia_size and ia_blocks in lookup, readdirp, etc
* wind fsync/flush on all shards
Note: Most of the items above are related. Once we come up
with a clean way to determine the last shard/shard count for
a file/file size and the mgmt of sparse regions of the file,
implementing them becomes trivial.
