* CI: use a docker image that includes Python
So that tests of abi-gen generating Python can exercise the code being
generated.
* CI fix: disable old yarn permission denied hack
Motivated by CI failure of previous commit.
* CI fix: more resources for test-contracts-ganache
Motivated by CI failure of previous commit.
* CI fix: remove hack of permissions for python libs
Fix for previous CI run's failure of test-python. Apparently we don't
need this in the docker container we've switched to.
* abi-gen/Py: minimum viable test of gen'd code
Ensure the code is parseable by running it through black.
* abi-gen/Py: expand Python linter usage
Make abi-gen filter its output through black, if its available in the
runtime environment. Accordingly, stop having contract_wrappers.py's
setup.py pre_install run black on copied-over files.
Adds Pylint to the list of linters run against test-cli/output.
* abi-gen: re-enable Solidity linter
It was broken, running seemingly cleanly but not actually reading any
files, because it was targetting the wrong folder.
* abi-gen/test-cli/fixtures/sol: fix linter errors
* abi-gen/test-cli: disable pylint blackisted-name
* abi-gen/Py: rm unused var in contracts w/o methods
Remove unused variable from generated wrapper for contracts without any
methods.
