As an JIRA Administrator I want to show to users JQL complexity of the Kanban boards

Problem Definition

This is related to performance problem described in https://jira.atlassian.com/browse/JSW-13211. A JIRA system has a maximum throughput of JQL's depending on the number of cores etc, DB, index etc. Kanban boards have a "JQL load score" (JQL complexity) based on the complexity of the query and the multipliers created by swimlanes+colours.
A system can become overloaded if too many Kanban boards with a high "JQL load score" are loaded in a short interval.

Suggested Solution

The system performance can be maintained if users that create boards are advised of their "JQL load score".

Workaround

Parse access log for slow requests and then review related Kanban boards
