Unnecessary API calls to back-end services are eliminated when checking
the quota and usage in individual panels. Each panel checks a resource
can be created by retrieving the current quota and usage for the resource.
However, the previous implementation retrieves quota and usage of unrelated
resources (For example, Nova usage is retrieved when checking a network
usage). It can be a performance problem in large deployments.
This behavior is now fixed to load quota and usage only for resources
which are really required.
