tooz doesn't use upper-constraints so we get the newest version of all
dependencies. It seems one of these, etcd3, is incompatible with recent
versions of protobuf.

_message.Message._CheckCalledFromGeneratedFile()
TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).
The etcd3 dependency is only used for the etcd3 driver which was
deprecated in change Iff0cd3b51cfc45ecbddc831c55267e80e9c79cac. The
protobuf dependency is only used for etcd3. We can't outright remove the
etcd3 driver yet as it hasn't been long enough since we deprecated it.
That will happen soon enough though and until then we can simply cap
protobuf to an older version that is compatible with the most recent
etcd3 release.
While we're here, we also sync the lower boundaries in the docs
requirments and add some comments indicating where they come from/what
they're for.
