Translate TOSCA description of instance capabilities to heat flavor
TOSCA template describe a server's capabilities by properties like disk_size, num_cpus, etc.. But hot template use a single flavor property. To cover this gap there're two options:
1. create a custom flavor by TOSCA description and use it while translating (but it requires admin role and there're lots of arguments of this topic)
2. query flavors from nova and pick the round one to translate.
Source the Openstack User credentials and use nova ReST API to fetch the flavor details and validate against the instance details

(spzala): Instead of using nova-client, I think we should use Nova REST APIs.
(spzala) We should not 'create' any new flavor. We only wants to query and find available best match flavor.
