[FEATURE] Parallel executor for Integrations installation

[RyanL1997]

Description

In version 2.14, we have introduced multiple integrations with the installation procedure of table creation -> materialized view index creation -> skipping index creation. However, this may take up to minutes, since all the above procedure was executed sequentially.

Ideally, after the table creation, instead of a sequential run for both mv index creation and skipping index creation, it can be a parallel run for these indices creation queries.

Solution

A implementation of a parallel executor would be a great improvement for speeding up the above installation procedure.
