Add pre-commit hooks for linting

[gsheni]

• This makes it so that linting is automatically run right before you commit code:
• We use this https://pre-commit.com/
• Example of this:
  
• More linting checks were added with the pre-commit-config
  • Strip out Jupyter notebook outputs
  • End of file fixer
  • removing trailing whitespaces
  • absolute important everywhere for EvalML
  • Add trailing commas
  • Run black[juypter] on py and jupyter files
