[JENKINS-58121] Use -- for long flags

It would be good to use long flags like how most other CLI tools use them

See:

i.e.

--

instead of

Usage could look something like:

jenkins-plugin-manager --file plugins.txt --jenkins-war jenkins.war --plugin blah --plugin plugin2 --plugin-directory plugins/

A couple of examples of how short flags could look:

jenkins-plugin-manager -f new-plugins.txt

jenkins-plugin-manager -p slack
