Single place to store/load cluster state
----------------------------------------
Key: WHIRR-246
URL: https://issues.apache.org/jira/browse/WHIRR-246
Project: Whirr
Issue Type: Improvement
Reporter: David Alves
Priority: Minor
Right now cluster state is written and read from the
~/.whirr/cluster-name/instances file and logic to write and update it is spread
between the Service and DestroyInstanceCommand (that I know of).
Since for WHIRR-214 the file must be updated (in another class) and for
WHIRR-238 an altogether different method of storing cluster state will be
required I think it might be time to move the read/write state logic to its own
file (or factory in the future).
I'll attach a very preliminary patch just to get some feedback.
