Hi All,

Latest convergence-poc code is available [1]
Reason for this fork was to avoid constant rebase. Wiki [2] also has been 
updated to reflect latest changes/deviations. One prominent deviation from 
convergence-blueprint is that observer and workers are not separate operating 
system processes, but eventlets under heat-engine.

A sample RandomString template used for verification is also available [3]. 
Verified for basic CREATE, UPDATE and DELETE operations. We are yet to verify 
ROLLBACK and CONCURRENT stack operations. Although we have tested using 
RandomString resource, Code should work for all heat resources.


1.       Delete old resources after a successful update

2.       Failure path for basic operations

We expect the poc completion by early next week.

Graph lookup code is all dumped on stack module and will look out of place and 
we intend to refactor them.
Please review code and share your thoughts.
