refactor: Use environments to install Conan

- Move previous conan/conan2 naming approach to Python environment
  solution.
  A wrapper that detects CONAN_SERIES environment var switchis between the
  two release series. Defaults to CONAN_SERIES=2.

- Enable profile creation support by default
  Passing environment var CONAN_CREATE_PROFILE=false will prevent to
  generate a default profile.
