Ability to define commands for a container

[seagyn]

For my application, I need to be able to define the commands/args I want the container to use to start up. For example, we have a container that uses the following command:

           command:
            - /usr/bin/catalog-admin
            - --config=/etc/catalog-admin/config.yml
            - --bind-address=0.0.0.0:9420
            - --tls-bind-address=0.0.0.0:9443
            - --cert-file=/etc/catalog-admin-tls/tls.crt
            - --key-file=/etc/catalog-admin-tls/tls.key
            - --ca-cert-file=/etc/catalog-admin-tls/ca.crt
            - --nats-secure=false
            - --nats-client-group=catalog-admin
            - --nats-cluster-id=eleanor-stan

It would be handy to have the ability to define commands and args that will be used for the container. A list of commands run in order and a list of arguments run in order.

Done.

Results in:

  containers:
    - args:
        - '-c'
        - while true; do echo hello; sleep 10; done
      command:
        - /bin/sh
