greenlight Features user settings PR

This PR should enable user settings features. What it does basically create a user specific settings so that user can create personalized setting when they join meetings. It basically use settings on https://docs.bigbluebutton.org/2.2/customize.html#passing-custom-parameters-to-the-client-on-join.

Description

What we change on the code:

We modify the create room and join room functionality to include the user join setting.
We create a new entity on database UserSettings that contains the user join setting, we also implement the functionality that enable users to modify the user settings, including with UI template, so there will be a new menu on the user profile.
We add a new setting on the .env file to setup which user join settings from https://docs.bigbluebutton.org/2.2/customize.html#passing-custom-parameters-to-the-client-on-join that we want to include.

Note: we currently specify this to only enable the skip check audio, skip video preview, auto share webcam and listen only mode. To enable more, just add more user join settings on the .env file and some additional entry on locales also might be needed

Testing Steps
