T3896: Drop cserv local user req, add groupconfig

From ocserv documentation:
```
If the groupconfig option is set, then config-per-user will be
overriden, and all configuration will be read from radius. That
also includes the Acct-Interim-Interval, and Session-Timeout
values.
```
Implement yes/no configuration and parameter handling during jinja
rendering.

Fix bug wherein openconnect-server configuration requires creation
of local user accounts even when RADIUS authentication is used.

Testing:
  Set the groupconfig=yes param and observed change in generated
/run/ocserv/ocserv.conf.
  Removed the local users via `delete vpn openconnect
authentication local-users` and observed commit & service operation
