Subject: vyos.util: add function to search a key recursively in a dictionary

data = {
    'interfaces': {'dummy': {'dum0': {'address': ['192.0.2.17/29']}},
                'ethernet': {'eth0': {'address': ['2001:db8::1/64', '192.0.2.1/29'],
                                      'description': 'Test123',
                                      'duplex': 'auto',
                                      'hw_id': '00:00:00:00:00:01',
                                      'speed': 'auto'},
                             'eth1': {'address': ['192.0.2.9/29'],
                                      'description': 'Test456',
                                      'duplex': 'auto',
                                      'hw_id': '00:00:00:00:00:02',
                                      'speed': 'auto'}}}
}

dict_search_recursive(data, 'hw_id') will yield both '00:00:00:00:00:01' and
'00:00:00:00:00:02' as generator object.
