[Deferred] Document Smart Query in Planner once implemented

[Preeticp]

https://openshift.io/openshiftio/Openshift_io/plan/detail/383
Query tab will need docs to describe the:

1. UX (GSG+UG) Query builder:

• Query for required WIs
• Create WI
• Ability to navigate WIs, their children and parents, use of breadcrumbs
• Export query results to CSV
• Iteration tree in Query tab

2. Query language/syntax (UG+contextual), the latter might also be linked to the UX as a quick help for users.

Add these features too once they are in:

• Create WI from the Links section(WIP)
• Rename WI fields (or add more fields?)(WIP)

As per: https://openshift.io/openshiftio/Openshift_io/plan?q=(typegroup.name:Execution%20$AND%20iteration:bcfb025c-a3c2-4578-a570-9a75c204845a%20$AND%20area:00682c61-905a-49b8-8f6f-0a90fb335aab)&showTree=true
