Managing Releases : Accessibility issues with tooltips in Releases page

Issue Summary

The popup which shows information regarding release is not accessible to screen reader users.

Steps to Reproduce

1. In the Jira dashboard, Navigate to the "Project " menu link in the header section.
2.  Select a "Scrum S/D" or any other project.
3. Navigate to the "Releases" link available in the left panel of the main content area.
4. In the "Releases" dashboard Navigate to the "Progress" section for different "Versions" in the main content area.

Actual Results

• The triggering element doesn’t have any role & name.
• While the popup can be opened with keyboard, when using JAWS screen reader it cannot be opened.
• The popup stays open and never closes when navigating away from it with a tab.
• When user press tab or shift + tab key focus goes to the end of page incorrectly. It is because the popup is coded at the end of DOM inappropriately.

Expected Results

• The triggering element should have role="button" & aria-label="1.0 release progress"
• When using any screen reader the popup should be opened with keyboard. 
• The popup should close when user tabs out of popup.
• When user press tab or shift + tab key focus should go to the logical elements. Ensure the DOM order of the popup is correct.
