feat: added pg_notify

[mkanoor]

Added an action to send notifications via postgres LISTEN/NOTIFY

This feature requires an updated ansible.eda collection with the pg_listener source plugin

Using this branch you can create an image with the new collection and push it to your private quay.io repo

• podman login quay.io
• podman build --no-cache --build-arg DEVEL_COLLECTION_LIBRARY=1 --build-arg DEVEL_COLLECTION_REPO=git+https://github.com/mkanoor/event-driven-ansible.git,pg_listener -t quay.io/<your_userid>/ansible-rulebook:latest .
• podman push quay.io/<your_user_id>/ansible-rulebook:latest

This will ensure that your image has the latest collection which can use the pg_listener source plugin in a rulebook.

LGTM. As a suggestion for an enhancement, the chunk logic can be encapsulated in a separate function, and it can have its own unit tests to ensure that the chunk logic works as expected.
