Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
Propagate the provided external CA certificate to the external CA object in swarm #1178

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. Signed-off-by: Ying Li <ying.li@docker.com>

--ca-certflag is provided, require a--ca-keyor--external-caflag beprovided 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 updatefunction to set the external CA's CACert field,which while not strictly necessary, makes the CA list more explicit.
As pointed out in moby/swarmkit#2680, the CA cert is not propagated correctly making it impossible to rotate the CA certificate to an external CA using the CLI.
This also fixes some other confusing ways the CLI worked previously.
