Pod Device-Read-BPS support
added the option for the user to specify a rate, in bytes, at which they would like to be able to read from the device being added to the pod. This is the first in a line of pod device options. WARNING: changed pod name json tag to pod_name to avoid confusion when marshaling with the containerspec's name Signed-off-by: cdoern <cdoern@redhat.com>
