OAuth implementation for existing gisida sites

[bcheye]

It has become a trend that all gisida projects are being implemented with OAuth. Some of these sites really don't need authentication since the data is public and the login credentials are displayed on the home page.
Do we need OAuth for public sites? We should probably have a discussion around which sites need OAuth and which ones doesn't need

@B-Cheye this is very true. We fell into this trap when we moved from superset to discover, we couldn't access discover dashboards without oauth. Since canopy supports public dashboards now, it would definitely be nice to drop oauth on all public sites.
