Description

I have the bin directory of Flink in my $PATH variable, so I can just do "flink run" on the command line for executing stuff.
However, I have multiple Flink versions locally and its hard to find out which installation the bash is picking in the end.

adding a simple "version" command will resolve that issue and I consider it helpful in general.
