Partial dh_python2 transitions

[Michael Terry]

Hello!  I was just considering how a dh_python2 transition for the 
various ubuntuone python modules would work.  They all install into the 
ubuntuone module, so would need to be updated at the same time.

Is there a recommended way to avoid the problem of users partially 
upgrading (either from builds finishing separately or specifically 
apt-get installing only some of the packages) and having mixed tool usage?

What have others done in this situation?  Breaks would work; just 
uploading close together would work if we think risk is low...
