feat(k8-operator): push secrets

[DanielHougaard]

Description 📣

This PR introduces support for pushing secrets from the K8 operator into Infisical. We are using policies for the replacement of existing secrets. This mean the user can opt-in to overwrite existing/conflicting secrets in Infisical, to treat the K8 operator as the source of truth.

The operator will automatically update the serverside secret values if it detects a drift has happened, even if the key of a secret changes. If a secret key changes, the secret will be deleted and re-created with the correct secret key. We do this by keeping a map of ID/secret-key, that we are verifying on each reconcile.

If the deletionPolicy is set to Delete, all secrets managed by the operator will be deleted once the InfisicalPushSecret CRD is deleted.

Additionally, we are now using a proper logger for all our CRD's. No more printf or println statements.

Need to application test. But some questions from my side

1. Was this library something we were using before go-logr because I feel like it's quite unused one and uber zap is the most prominent one in this space.
2. Nit: Some messages starts with sentence case while others in small case

Something is wrong, it keeps updating secrets even though there were no secrets updated

Issue: The secrets that are created by the operator keep being updated (so the number of secret versions keep going up). If there aren't any changes, we shouldn't make a update.

For future PRs, i recommend doing a separate PR to do folder restructure first and get it merged. This helps to reduce the surface area of pr testing and allows us to merge prs quicker.

Testing i did:

• auto secrets auto redeploy
• delete managed secret
• add new key and have it synced

Need to do more testing on secret push after the update bug is patched.

For docs:

• I think we now have too many things in one page. Let's break it up into another sub page of k8s integration page

When deletionPolicy: Delete and you delete the kube secret, this is what i see:

The secrets in Infisical are not deleted
