Implement Secrets
Implement podman secret create, inspect, ls, rm Implement podman run/create --secret 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 Signed-off-by: Ashley Cui <acui@redhat.com>
