Vipin Balachandran 383c37e0d8 Fix release notes formatting
We use double ticks to format config options, driver FQNs
etc. in few release notes to improve readability. This
patch updates the remaining release notes to follow the
same convention.

features:
- Added a new config option ``scheduler_weight_handler``. This is a global
option which specifies how the scheduler should choose from a listed of
weighted pools. By default the existing weigher is used which always
chooses the highest weight.
- Added a new weight handler ``StochasticHostWeightHandler``. This weight
handler chooses pools randomly, where the random probabilities are
proportional to the weights, so higher weighted pools are chosen more
frequently, but not all the time. This weight handler spreads new
shares across available pools more fairly.
