Added option to disable webhooks (#13176)

* Added option to disable web hooks

This mod introduces DISABLE_WEB_HOOKS parameter in [security] section
of app.ini (by default set to false). If set to true it disables web
hooks feature. Any existing undelivered web hook tasks will be cancelled.
Any existing web hook definitions will be left untouched in db but
its delivery tasks will be ignored.
