Karthikeyan Chinnakonda 32a316aef7 server: provide an option to enable event triggers on logically replicated tables
## Description ✍️
This PR introduces a new feature to enable/disable event triggers during logical replication of table data for PostgreSQL and MS-SQL data sources. We introduce a new field `trigger_on_replication` in the `*_create_event_trigger` metadata API. By default the event triggers will not fire for logical data replication.

## Changelog ✍️

__Component__ : server

__Type__: feature

__Product__: community-edition

### Solution and Design
- By default, triggers do **not** fire when the session mode is `replica` in Postgres, so if the `triggerOnReplication` is set to `true` for an event trigger we run the query `ALTER TABLE #{tableTxt} ENABLE ALWAYS TRIGGER #{triggerNameTxt};` so that the trigger fires always irrespective of the `session_replication_role`
- By default, triggers do fire in case of replication in MS-SQL, so if the `triggerOnReplication` is set to `false` for an event trigger we add a clause `NOT FOR REPLICATION` to the the SQL when the trigger is created/altered, which sets the `is_not_for_replication` for the trigger as `true` and it does not fire during logical replication.

### Steps to test and verify ✍
- Run hspec integration tests for HGE

## Server checklist ✍

### Metadata ✍

Does this PR add a new Metadata feature?
-  Yes
  - Does `export_metadata`/`replace_metadata` supports the new metadata added?
