offload better exception traceback from sensitive data

[abom]

Because sometime, the exception is shown with the value of sensitive variables.

We can offload this data based on some keywords or certain keys.

Also data of logs/alerts if have any sensitive keys.

we need to check this section https://github.com/Qix-/better-exceptions#advanced-usage for preventing the leaking

We need to choose between keeping it in production with offloading/truncation or just move it to development dependencies and only use it if imported or debug flag is set to False in configuration.

don't see it as a pressing matter now
