Is your feature request related to a problem?

We'd love to use DDEV_SHARE_URL for various things inside web container. Currently it's available in host context, and is very nice there.

For example, we could use DDEV_SHARE_URL to override DDEV_PRIMARY_URL (or use instead) in WordPress wp-config-ddev.php and there would be no need to fiddle with that.

Describe your solution

I don't know how to cleanly do this. For PHP it would require restart of php-fpm. For other contexts, who know?
