Title: add the functionality to start the tagging process when the current build was not successfully. 

add the functionality to start the tagging process when the current build was not successfully.
For this feature a new checkbox was added to the project specific
configuration. The default value is checked. When the value is unchecked
the tagging process started regardless of the build state. In some
situations it is helpful when the tagging starts without the success
condition.
