Upgrade to Pants 2.10.dev3

The main change is switching to the new `[python].enable_resolves`, which allows us to have Pants generate the lockfile for us and use `--hash`!

This also applies pantsbuild/example-python#90.

 # example-codegen
+
 An example repository to demonstrate codegen support in Pants. 
+
+Refer to these docs for more information:
+
+* [Python Protobuf](https://www.pantsbuild.org/docs/protobuf-python
+* [Python Thrift](https://www.pantsbuild.org/docs/protobuf-python
+
+Run `./pants export-codegen ::` to see the generated files. This isn't necessary for Pants to 
+use the generated files, but can be useful when debugging or to generate files for IDEs.
