io-threads: Support autoscaling volfile options
This commit finally makes the autoscaling feature visible to the user. Know that we're now using two separate thread-pools, one for data requests, called ordered thread-pool in io-threads, and the other for meta-data requests, called un-ordered thread-pool. We do not expose this information to the user to keep io-threads simple. Consequently, when the user specifies a min-threads and max-threads value, the number of threads assigned to each pool is equal, i.e. both pools start with their min threads set to half of the option "min-threads" and both scale up their threads at most up to half of option "max-threads". Volfile options will be added to the wiki and user-guide. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
