This patch set accomplishes 2 things:
1) Fixes an issue in Deckhand caused by improperly using the wrong
Barbican secret type for the PrivateKey Deckhand document type.
2) Tests all Deckhand secret types against Barbican via integration
testing.
The current error being raised is this: "Provided object does not match
schema 'Secret': u'privatekey' is not one of ['symmetric', 'passphrase',
'private', 'public', 'certificate', 'opaque']."
