Ability to add an description/note from xml test file

[ghost]

Is your feature request related to a problem? Please describe.
It's not a problem, I want to describe my tests from xml file, to help my team with investigation/find an purpose of tests.

Currently we have an ability to set up it on aet results file, but those notes need to be added manually (and when database will be cleared those notes will also dissapears)

Describe the solution you'd like
A new markup in xml file, like <description>"Should be open dashboard page"</description>

 	<test name="Test">
            <description>"Should be open dashboard page"</description>
 		<collect>
 			<resolution width="1280" height="700"/>
			<open/>
                         <wait-for-element [....]/>
