cli: add repo.py object

A user can list repos using "ogcli list repos":

$ ogcli list repos
{
    "repositories": [
        {
            "id": 1,
            "ip": "10.141.10.1",
            "name": "Repositorio (Default)"
        },
        {
            "id": 3,
            "ip": "127.0.0.1",
            "name": "dummy"
        },
        {
            "id": 4,
            "ip": "192.168.21.21",
            "name": "helloworld"
        }
    ]
}

The repository of a client or group of clients in a room is configured
using "ogcli set repo --id <id> [--client-ip <ip address>, --room-id
<room id>]:

$ ogcli set repo --id 4 --room-id 1
