chore: Add py37 warning

[setu4993]

During the import of dataquality, start warning users that we're going to be dropping Python 3.7 support soon.

Why in the Analytics init? What not in dq.init or in the __init__.py file when you import?

@elboy3 :

I put it here because that's where we were logging the version to Amplitude for. I personally prefer putting it in __init__.py but wasn't sure if that'd be okay. Can move it there.

@setu4993 I think i'd prefer that, since we might remove amplitude in the not so far future as well

Fair enough, done.
