Description John Spray 2017-06-26 09:46:51 UTC

A manager module that runs on demand, or in the background, to adjust CRUSH weights based on OSD utilisation, in small enough increments to avoid excessive data movement.

Should satisfy two use cases:
 * Fixing statistical OSD imbalance to avoid one drive going full too soon
 * Automating gradual weight-in/weight-out of drives so that administrator doesn't have to personally keep adjusting weight.

Not started yet upstream, but should be backportable.

Updating the QA Contact to a Hemant. Hemant will be rerouting them to the appropriate QE Associate.

This is the balancer module.
