Currently, the SD Project's queue page loads all queue's JQL issue count prior to rendering the whole page.
This results in the whole page loading slow if there's a single queue with a slow underlying JQL.

If each queue is rendered (or it's respective issue count) is rendered asynchronously on the screen it won't affect the overall usage of the project queue page.

This is a different approach to https://jira.atlassian.com/browse/JSDSERVER-6424, yet both address the same symptom that is a slow loading project queue page.
