Motivation
We use sonarqube at my organization so it would be great to support it.

Summary of desired enhancement
A few things needed:

• Need a CI already configured - we will add to any (supported) we find; just bitbucket to begin with via if-statement
• 3 environment variables to be set: the Host URL, Token, and the project key. These should be entered at the bitbucket (or whatever) level, and the user should be informed accordingly.
• Create a bespoke configuration file sonar-projects.properties. Rather than having this sit in version control, as suggested in a comment below, the information could live in pyproject.toml and then get exported to the sonar-projects.properties file dynamcially in CI.
• For Bitbucket: use a pipe (similar to pre-commit hook - points to an external repo) from here: https://bitbucket.org/sonarsource/sonarqube-scan/src/master/
• Configure the pipe in each CI config to accept the relevant information from the 3 environment variables and to point to the properties file
• Need to hard-code the versions of Python supported - fine, we already do this with Bitbucket anyway. Re-running usethis tool sonarqube with a change to the supported versions should update the config file in the relevant sonar.python.version field.
• Should be added to the bitbucket pipelines as a final step.
