4.0.0

• (breaking) Drop gradle 5 and 6 support
• (breaking) All plugin tasks become abstract, so any custom task types should be abstract too
• (breaking) All tasks use lazy properties instead of convention mapping (affects custom tasks)
• Fix alwaysInstallModules = true not triggers pipInstall for non-strict requirements file (#94)
  (required for case when requirements file links other files, which changes are not tracked)
• Add requirements file references (-r file) support under strict mode (#94)
• Configuration cache compatibility (#89)
• Changed virtualenv version installed by default (python.virtualenvVersion) from 20.4.2 to 20.25.1
  (supports python 3.7 - 3.12)
• Changed default docker image (python.docker.image) from python:3.10.8-alpine3.15 to python:3.11.8-alpine3.19
• New options (python.):
  • breakSystemPackages: adds --break-system-packages for pip install
    May be required on linux to install virtualenv on apt-managed python (e.g. python3.12)
  • docker.useHostNetwork: use host network for docker
    Works only on linux. When enabled, all container ports automatically exposed on host
    and configured port mappings ignored
  • printStats: show all executed python commands (including plugin internal) at the end of the build (with timings)
  • useVenv: use venv instead of virtualenv (enabled by default)
    Venv is installed by default since python 3.3 which removes requirement to install virtualenv. (#77)
    Fallback to virtualenv when venv not found. All current environments created with virtualenv
    will still be working correctly.
• Add user home dir ("~/") support for the environment path (python.envPath)
• To use different python for PythonTask useCustomPython = true must be declared now
  (otherwise, pythonPath select by checkPython task would be used (and task's pythonPath ignored))
