    Store AccessKey secret_key in resource data

    Similar to the change for SignalResponder, store the secret key
    encrypted in resource data, rather than requesting it from keystone
    every time the user requests the SecretKey attribute.

    Unlike SignalResponder (which stores the signed URL after using
    the keypair to sign the request), we need this to be backwards
    compatible, to cope with upgrading heat with stacks in the DB
    which contain the AccessKey resource but don't have the secret
    stored.
