The settings CORS_ALLOW_ALL_ORIGINS was set to True by default.
This error is inherited from a old mistake made back in the days
while working on the initial impress demo.
I wrongly configured the settings. This error was propagated when
@sampaccoud copied impress code to kickstart LaSuite Meet.
This is not something we want, this should be only allowed in
development. We change the value in all the manifests in order to have
the desired behavior in non development environments.
