Add TQDM progress bar for Jupyter Notebook pandas_to_eland() calls

[sethmlarson]

• https://github.com/tqdm/tqdm#ipythonjupyter-integration
• Units are rows/s
• Maybe hide progress bar on completion? Need to test it out first.
• Add an option show_progressbar which defaults to None
  • If None show a progress bar only if we detect Jupyter Notebook
  • If False don't show a progress bar
  • If True show a progress bar only if we detect Jupyter Notebook (for now)

I'll try to implement this and get a gif to show for you. 😬

@sethmlarson I tried an example in jupyter notebook

Need suggestion on this:

• from tqdm.notebook import tqdm => It only works in jupyter notebook , not in jupyter lab, terminal

In jupyter lab, It throws the following:

I had the same scenario for from tqdm.auto import tqdm

Looks like there's already an issue in tqdm

Still currently exploring different options of tqdm 😄

My Queries are:

• Is it Ok, If we just do for jupyter notebook ?
• For testing this, Should I go with pytest --nbval to match the output?
