[CICD-24] Improve performance by utilizing pre-built Docker Image.

JIRA Ticket

CICD-24

What Are We Doing Here

Building and hosting image on WPE docker hub, then calling the hosted image instead of building it every time.

Original: Avg 11-14 seconds (Build Docker Container on the fly)

New: 4 seconds :tada: (Build Docker Container from Hosted Docker Image)

NewNew: 1 second 🐎 (Pull Docker Image directly from within action.yml)

New SPLIT: 4 seconds ⏩ (Build Docker Container from Hosted Docker Image, but split to add in exclude.txt and entrypoint script afterwards)

Plan Moving Forward:

• We're going forward with the "Split" image approach - where base-stable is hosted in Dockerhub and imported as a directive into the main Dockerfile for the project. Additional directives and other frequently updated file inclusion are added below the image.

TO DO:

• [ ] Automate rebuilding the base-image

• Restore the DockerHub Build Rules

• [ ] Automate building custom images on the fly based on branch name with regex

• See ideas in the DockerHub Build Rules

• [ ] Optimize the Base Image
