OVERWRITE_SETTING of Jitsi App doesn't work from 5.0

[TheRealBro]

Description:

With the change / update of video conferencing - Jitsi Settings are no longer read from environment variables.

Steps to reproduce:

Download docker container and try to start with the following environment variables:

OVERWRITE_SETTING_Jitsi_Enabled=
OVERWRITE_SETTING_Jitsi_Domain=
OVERWRITE_SETTING_Jitsi_URL_Room_Prefix=
OVERWRITE_SETTING_Jitsi_Enable_Channels=
OVERWRITE_SETTING_Jitsi_Open_New_Window=
OVERWRITE_SETTING_Jitsi_Chrome_Extension=
OVERWRITE_SETTING_Jitsi_Enabled_TokenAuth=
OVERWRITE_SETTING_Jitsi_Application_ID=
OVERWRITE_SETTING_Jitsi_Application_Secret=

Expected behavior:

When I install the Jitsi App from the new App marketplace, it should be possible to set the App settings via Environment variables, to start the docker container with the correct settings.

Bonus points, if we could install Apps like Jitsi App via an environment variable from the Marketplace, while starting the container.

Actual behavior:

Settings stay empty and need to be set by hand.
