Sebastiaan van Stijn b9a7f35e02 Singularize / pluralize "argument(s)" in error message
The validation functions to test for the number of passed arguments did not
pluralize `argument(s)`, and used `argument(s)` in all cases.

This patch adds a simple `pluralize()` helper to improve this.

Before this change, `argument(s)` was used in all cases:

    $ docker container ls foobar
    "docker container ls" accepts no argument(s).

    $ docker network create one two
    "docker network create" requires exactly 1 argument(s).

    $ docker network connect
    "docker network connect" requires exactly 2 argument(s).

    $ docker volume create one two
    "docker volume create" requires at most 1 argument(s).

After this change, `argument(s)` is properly singularized or plurarized:

    $ docker container ls foobar
    "docker container ls" accepts no arguments.

    $ docker network create one two
    "docker network create" requires exactly 1 argument.

    $ docker network connect
    "docker network connect" requires exactly 2 arguments.

    $ docker volume create one two
    "docker volume create" requires at most 1 argument.

Test cases were updated accordingly.
