Include UI build in setup.py build command

[alberttorosyan]

Proposed refactoring or deprecation

Add the following steps to python setup.py build command:

npm i
npm run build

Motivation

Currently when running aim from source installation it requires to run UI build manually, which often is forgotten.

Pitch

Need to make sure aim package (both UI and backend/SDK) can be build/installed with a single command. pip install -e . from aim source directory should produce desired result.
