Description

All state store implementations support adding multiple state store records using single putAll() implementation. We should provide new router admin API to support bulk addition of mount table entries that can utilize this build add implementation at state store level.

For more than one mount point to be added, the goal of bulk addition should be

1. To reduce frequent router calls
2. To avoid frequent state store cache refreshers with each single mount point addition
