Use 'wsgicors' for CORS handling. The CW CORS handling (in web/cors.py) is only able to work on cubicweb requests. When a request is not handled by bwcompat, we need a proper solution. The `wsgicors` library provides what we need as a wsgi middleware.

Watch for i18n files changes for auto-reload

Auto-reload now survives failed reload When the server stops within the reloader and let a list of files that were monitored, the reloader waits for any of these files to change and re-attempt to start the server. This work well when a syntax error is saved to a file: there is no need to restart manually the server anymore.

Implements auto-reload and daemon mode. Heavily inspired by pyramid pserve, with pieces of code taken from it. auto-reload Start the server in a subprocess that auto-stops when a file is modified, and exit with a specific code. daemon mode Uses some code from pserve, but use the cw configuratione so the command is compatible with 'status' and 'stop' commands.

Add the 'pyramid-auth-secret' option to all-in-one.conf

Add the 'pyramid-session-secret' option to all-in-one.conf This value is used by pyramid_cubicweb to initialize the cookie factory.

Add a CWSession entity. It is a subset of the CWSession that will be added to cubicweb in a future version. Closes #4317363

Implements the 'pyramid' command. It load an instance config, and load in the pyramid scaffolding provided by pyramid_cubicweb. The application is then served by a waitress server. Closes #4317312
