Support CCI instance resize

[bodenr]

The ability to resize an instance (CCI) is an important aspect to managing compute. This feature is obviously supported in native nova instances, but no such support exists in jumpgate.

This issue/enhancement is intended to track that support -- adding the ability to resize a CCI a la jumpgate.

@bodenr :the CCI resize is implemented and am waiting for it to be merged in softlayer-client[1]
so upgrade/resize will support CPU and memory,
any thoughts on how should we proceed further on resize with respect to disk?
Can we let the user now for the time being as a note of some sort in doc block that disk will not be upgraded?[

@swapnil90 that's great news about mem/cpu resize...

yes I think you guys could consider adding a note to the jumpgate compatibility matrix about whats supported and what's not from a resize perspective.. I was looking at the nova code / docs trying to see if there was a way to return info about extensions to indicate from an API perspective this wasn't supported, but it's not entirely clear to me without more digging.

@bodenr : i had also looked into openstack API and such for passing/giving info to user, but didnt find it either.
I had a query regarding disks mentioned in flavor, they are all local right and not SAN?

[bodenr]

@swapnil90 - If I understand your question you are asking jumpgate only supports LOCAL disk right now? If so the answer (last time I checked) is only LOCAL disks are supported at the present moment..
