Description

to allow faster execution of bootstrap dump phase we dump multiple partitions from same table simultaneously.

even though dumping functions is not going to be a blocker, moving to similar execution modes for all metastore objects will make code more coherent.

Bootstrap dump at db level does :

• boostrap of all tables
  • boostrap of all partitions in a table. (scope of current jira)
• boostrap of all functions
