in swarm.
Also, fix some CLI command confusions:
1. If the --external-ca flag is provided, require a --ca-cert flag as well, otherwise
the external CA is set but the CA certificate is actually rotated to an internal
cert
2. If a --ca-cert flag is provided, require a --ca-key or --external-ca flag be
provided as well, otherwise either the server will say that the request is
invalid, or if there was previously an external CA corresponding to the cert, it
will succeed. While that works, it's better to require the user to explicitly
set all the parameters of the new desired root CA.
This also changes the `swarm update` function to set the external CA's CACert field,
which while not strictly necessary, makes the CA list more explicit.

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.
