On each plugin initialization we create a separate python interpreter which gets stored in the plugin_ctx. The main interpreter is stored in py_ctx and is used for creating more interpreters (if more plugins get loaded) and final python deinitialization. The "traceback" module import and the ImportBlocker initialization was moved, because it has to happen inside the plugin specific interpreters.
