------------------------------------------------------------------

Updated PHOENIX-3853 with results for mutable local index. For mutable case there is no 2X
degradation comparing mutable local vs global index *without* PHOENIX-3827 patch applied.

> While preparing index mutations we are are scanning data region for index maintenance
which is not required in case of immutable rows. This optimisation is very helpful for local
indexes which got removed in the recent changes.
