Upgrade the helm chart with subcharts to make it more versatile

[InputObject2]

Is your feature request related to a problem? Please describe.
Currently the helm chart is in an MVP state, where we setup a minimum mongo, redis and checkmate deployment. It allows very little in the ways of customization.

Describe the solution you'd like
Instead of defining resources directly in our templates, we would override them using standard sub-charts.

Mongodb -> bitnami/mongodb
Redis -> bitnami/redis
Checkmate itself -> bjw-s-labs/app-template

We should also be able to turn off components in order to deploy them ourselves (for example with mongodb.enabled: false)

Additional context
This feature needs to also update the documentation to reflect the new charts and their values and how to configure them.

hi @gorkem-bwl , I m interested to work on this issue.
From what I can understand, it involves integrating sub-charts with component toggles, docs updates. could you confirm and share more context or refs if any? also ig will have to work with security and testing as well. Thank you.

TBH I really dont have much expertise, if not "none", with Helm charts. I believe what @InputObject2 asks is on par with what you propose here. So go ahead - when you are done, if you can give some details about work and benefits, that would be awesome.

thank you, will update my findings here as well.
