As a user, I can use a Requirements List gadget

A new JIRA gadget "Requirements List" should provide a list of requirements and their coverage status.

Aim: see how a group of requirements, of some project, are for a given version, or test plan. the current possible way to list requirements in a gadget could show the requirement status, by using the "Requirement Status" custom field, which shows the coverage status only for a version (which depends on the general configuration in Xray).

Filters:

• project (mandatory)
• saved filter (for further restrict the requirement issues of the given project)
• Status of requirement (options: OK, NOK, Not Run, Unknown, Uncovered)

Analysis:

• testplan or version
• test environment

Gadget Title: by default "Requirements List" but may be customized (if possible)

Sortable columns: Key, Summary, Version

Notes:

• Passed counts all Tests whose current status contributes to the OK of the requirement
• Failed counts all Tests whose current status contributes to the NOK of the requirement
• Other counts all other Tests
• the test counts should be clickable and redirect the user to the issue search screen.
