Transition to pyproject.toml and setup.cfg

[eccabay]

Closes #3412

Also removes the concept of core-requirements within evalml. The core-requirements file still exists should users want to download evalml without catboost and xgboost, but there are no more tests or integrations for it. Ideally we'll remove this entirely in the future.

@eccabay Glad to see this happen for EvalML. You can delete MANIFEST.in and move it to setup.cfg

• alteryx/featuretools@74bfdb4
  You can also move additional things to pyproject.toml (like pytest, isort, coverage run/report). See above link

[gsheni]

this can be moved to pyproject.toml

@eccabay I think we also need to update release.yml to use version 2 of the upload to pypi action like woodwork did here:
alteryx/woodwork@e81dc64#diff-87db21a973eed4fef5f32b267aa60fcee5cbdf03c67fafdc2a9b553bb0b15f34R13

[freddyaboulton]

Thank you @eccabay for sticking with this and thank you @gsheni for helping out for the review. Left some small comments. Should be good to merge after that.

[freddyaboulton]

Why was this deleted?

[eccabay]

Plotly moved from being a core-requirement to one of the regular requirements. self.plot is only None if plotly isn't installed. Since we no longer test this case, I removed this to make codecov happy (and users that pip install us shouldn't have an issue regardless)

[freddyaboulton]

Looks good to me @eccabay !
