[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
