[pyramid/ctl] add a new option to activate the debugtoolbar (-t) While this toolbar isn't yet very integrated with CW, it integrates an inline debugging shell like werkzeug for flask or django_extensions which greatly helps debugging on exception. It can already be manually activated by writting "pyramid.includes = pyramid_debugtoolbar" but it's hidden somewhere in the documentation and not very accessible and annoying to do. Closes #17219765
