--docker option does not work

[tchinchow]

There is some code that parse the "--docker" option in the manage_images script however it can never be used because the previous call to getopt does not include the 'docker' option.

-> need to add docker to the list of allowed long options in the call to getopt

Hope it helps...

P.S. BTW : why parsing options both manually and with getopt instead of using getopt all the way ?

Right, there was a typo from when I added the podman support, as docker was going to still remain as the default. But I didn't remember to adapt getopt.

Fixed by #7

I am not sure what you mean? Getopt returns an array, which what the while parses.

But I will be happy to learn a more efficient way. Please feel free to submit a PR.
