removes unused packages files

[anthonyduong9]

Problem

• .gitlab-ci.yml, .travis.yml, .github/ are unused, since CI is in .github/ in the root directory.
• git_push.sh seems it's meant to be used when the client is in the root directory.
• test/ contains auto-generated test functions that don't do anything, and get deleted upon generation anyways.
• tox.ini and test-requirements.txt only matter for test/.
• setup.cfg only matters for flake8.
• requirements.txt is redundant with setup.py.
• .openapi-generator-ignore just has comments, and gets deleted upon generation anyways.

Fix

• Adding files to skip during OpenAPI Generator code generation, to schemas/.openapi-generator-ignore.
• Passing schemas/.openapi-generator-ignore to --ignore-file-override in each openapi-generator generate command.
• Running make setup-all-autointerp VERSION=1.0.0 and make setup-all-inference VERSION=1.3.0.

Testing

I re-ran make setup-all-autointerp VERSION=1.0.0 and make setup-all-inference VERSION=1.3.0.

@hijohnnylin if you merge this, I suggest you do it before you merge #84, which increments the minor version.

This is only for the autogenerated clients right? If so I'm fine with having these extra files.
