Unable to retrieve process logs

[cc-a]

Whilst attempting to retrieve process logs via ProcessManagerDriver.logs I got the below backtrace. Looks like some missing imports in grpc_utils.py. I did have a play around to include the imports and encountered further complaints about protobuff datatypes so there seems to be a wider issue at play.

Hi Christopher, which version of drunc are you using? The log endpoint seems to be working for me.

Thanks @plasorak. Managed to resolve this as a mistake on my part but would be nice to fix this up as the errors were a red herring.
