Remove external dependencies that are tightly integrated into the Mojaloop Helm Chart

[mdebarros]

Goal:

As a Mojaloop Deployer

I want to remove all external Helm chart dependencies from the Mojaloop Helm chart

so that deployers are able to manage the external dependencies separately

Acceptance Criteria:

• Helm Charts no longer have external dependencies (Kafka, MySQL, MongoDB, Grafana, etc)
• Mojaloop Umbrella Helm Charts are deprecated (i.e. Promfana, EFK+APM)
• Deployment Guide is updated to include:
  - a list of external dependencies as pre-requisites
  - instructions or links provided on how they can be deployed using Helm (or alternatively additional guides on how to use managed servers in AWS, Azure, etc can also be considered)
  - instructions on how to configure Mojaloop charts to use these external deployed dependencies (i.e. Kafka URIs, etc)
• Update Helm Chart documentation to reflect this change.
• Updated Deployment Guide instructions are tested by QA

Complexity: Medium

Uncertainty: Medium
