booster: attr_timeout: Read timeout from booster fstab
In order to expose the timeout values for stat and inode caching, this commit introduces a new fstab option "attr_timeout" that defines the number of seconds for which a looked up inode or a stat()'ed structure is valid in the cache. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
