Merge remote-tracking branch 'origin/master' into configure-ports-247

Conflicts:
	flocker/node/_deploy.py
	flocker/node/_model.py
Fixed broken import
Default proxies on StateChanges
Passing tests for deployer init setting _network
Improved test name
Explicit that no_state_changes includes proxies
Start of test for ports_to_create

Start of test for proxy needs deleting
Start of having all proxies enumerated
Set of proxies now doesn't break
Improved TODO
