As a user, in a Test Execution I should be able to see the requirements linked to a Test

We should be able to see a list of Requirements/Defects in proper columns, by keys delimited by comma (e.g. XPTO-1, XPTO-2).

Note: Currently we are only able to see the number of requirements (i.e. #Req) or the number of defects (i.e. #Def)
