PROPOSAL: Add Codacy to check code quality

[noelmiller]

Since we are considering splitting out our container files into smaller bash scripts (rather than doing inline bash), I think it would be helpful to have a code analysis tool to help with consistency and code quality: https://www.codacy.com/pricing

The open source plan is free and it can be added as a check in Github on a repo.

See https://github.com/JasonN3/build-container-installer/pull/100 as an example.
