Add the SECRET keyword to the shell completion test. Also update the
use line for podman secret create to use `NAME` instead of `SECRET`.
This matches the other commands such as network/volume create.

Secrets are blobs of data that are sensitive.
Currently, the only secret driver supported is filedriver, which means creating a secret stores it in base64 unencrypted in a file.
After creating a secret, a user can use the --secret flag to expose the secret inside the container at /run/secrets/[secretname]
This secret will not be commited to an image on a podman commit
