Description of problem:
Generally, there are several hundreds of cases in one TCMS test plan, but not all of them be covered in one time testing. We need to make sure all the cases be covered during each release, thus the filter of "Run times" and "Run period" are requesed to trace this kind of cases.

 Run times: ___[$run-times]___ 
 Run between: ___[$start-date]___ and ___[$end-date]___

 For $run-times, valid input values:
 0 -- The cases do not run
 n -- The cases has run "n" times(n>=1)

 For $start-date and $end-date:
 - with the format YYYY-MM-DD or relative dates
 - default value of $start-date is when the plan created
 - default value of $end-date is Now

Version-Release number of selected component (if applicable):
