Trouble accessing generated DSA keys using CLI

Steps to reproduce:

1. Generate a DSA key:
    openstack secret order create --bit-length 1024 --algorithm DSA --name "DSA key" asymmetric

2. Using the order href from the output from step 1, get the order details:
    openstack secret order get http://<order ref here>

3. Using the container href from the output from step 2, attempt to get the container details:
    openstack secret container get http://<container ref here>

Expected Result:
    the container details

Actual Result:
    "Unknown container type "dsa"."

It seems that barbican must create a container of type "dsa", which is not in barbicanclient's container_map. See https://github.com/openstack/python-barbicanclient/blob/49505b9aec05ec42e0a809ec51935c2324d5f3a6/barbicanclient/v1/containers.py#L521-L525
