missing def for general.topology_prefix in config.json

[saroj-lbl]

Hello,

With the following added to site_configuration

'general': [
    {
        'topology_prefix': configdir+"/topology",
    }
],  

I get the following error when running a test

ERROR: failed to load configuration: could not validate configuration files: `<builtin>`, `config/lrc.py`: 
Additional properties are not allowed ('topology_prefix' was unexpected)`

This is likely because topology_prefix is missing from general\items in schemas/config.json; it is only present in defaults.

Indeed, that's a bug, thanks for catching it!
