datetime.datetime is not JSON serializable

[Sergey Skripnick]

Unable to retrieve secret in json format using cli. Steps to reproduce:

1. Create a secret:

barbican secret store --name cert-1 \
    --secret-type certificate \
    --payload "$(cat delme-1.pem | base64)"

2. Try to get it in json format:

barbican secret get -f json \
      http://SECRET-URL/....

{
  "Status": "ACTIVE",
  "Name": "cert-1",
  "Algorithm": "aes",
ERROR:barbican:datetime.datetime(2017, 2, 6, 11, 3, 49, tzinfo=<iso8601.Utc>) is not JSON serializable

This should be a barbicanclient bug and also occurs when retrieving json format of acl/ca/order/container
