Pre-commit hooks not looking out for print statements

[thesujai]

Observed behavior

Reference: #11978 (comment)
Currently the precommit hooks are not detecting print statements in our code base, and there are many of them that have made into our codebase.

Expected behavior

• Pre-commit hooks should fail if any print statements(without noqa comments) are there in the code.(Introduce flake8-print)
• Wherever there are print statements in codebase, they must be either replaced by logger or noqa comments should be added to them

User-facing consequences

Developers using print statements for testing and debugging miss out some print statements while commiting. So the pre-commit will stop them from doing so.

Steps to reproduce

Run the pre-commit on all files, you can see everything pass, but there are many print statements throughout codebase

Context

Observed on develop but same for elsewhere

I would be happy to raise a PR for this.
Just a confusion where to use noqa and where to use logger

@thesujai I'll assign you. I think most existing usages of print would have to be migrated to use logging, unless it seems clear it was accidentally added for debugging
