`git pw patch update` is too slow

Rather the point to confirm than the bug.

Just a side note: I have git pw and pwclient running on different machines, surprisingly the former is run on way much more powerful machine (44 cores server vs. 4 cores desktop).

I suspect this is because the XML-RPC API allows for bulk updates, while the REST API does not support this. I need to think about how to do this from the server side. Perhaps allowing updates for series and bundles instead of patches would be a suitable workaround?
