When `delete_nodes` is given a large amount of nodes, or is instructed to recursively delete a big structure, the connection between client and server can time out. To remedy this, allow the user to supply a `batch` parameter, which controls how many nodes are deleted in one request. closes FreeOpcUa#1148

why does that help? the client must anyway wait for all chunks to be processed isnt'it? |

Indeed, in the end the client must wait until everything is processed on serverside. However, when deleting large structures, using python-opcua as client and as server, the delete operation will time out, because the server takes to long to process the single request. Allowing to batch these into managable chunks will at least keep the network-side working, and the requests themselves won’t time-out. |
