Thank you.
I didn't reuse the parser there because there is an ongoing JIRA to unify
all the command line parsers inside Flink. It seems that we are using at least
two different libraries .. and the consensus in the JIRA seems to be using a
third one to solve the problem.
But I didn't want to add more confusion to the topic than we already have.
