Break out chart installation by Harness Mode

• Platform (core components that are always deployed) - minio, mongo, redis, timescaledb, gateway
• CI - everything in the chart/templates/ci/ folder
• NG - everything in the chart/templates/cg and chart/templates/ng folders
• CI-NG - everything in the chart

The purpose of this ticket is to permit the above components to be installed based on what the user supplied for the "harness_mode" top level variable.
