🛠 Guidelines to remediate hardcoded secrets

1. Understand the implications of revoking this secret by investigating where it is used in your code.
2. Replace and store your secrets safely. Learn here the best practices.
3. Revoke and rotate these secrets.
4. If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.

To avoid such incidents in the future consider

• following these best practices for managing and storing secrets including API keys and other credentials
• install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.

.env will still be there. Let's get on a call to explain more. I think there is some mis understanding.

Also, let's do this service by service, instead of one big PR. Also go more into different env blocks in docker compose

Hey @tushar5526. As an initial PR, I have covered a few services in this one and tried to finalaise them.Since these didn't have much env vars of their own, so I just restructured the env a bit and removed docker env-file attribute from all of them. I wasnt sure about the redis one but on testing I found out that it works just fine without the rest of the env vars, so they are'nt necessary for it's functioning. Do let me know if I missed something.
