SignalResponder could leak users

[Steven Hardy]

SignalResponder only sets the resource_id if we manage to create an ec2 keypair, meaning that we will leak users in the event that creating the user works, but creating the keypair does not.

    SignalResponder, set resource_id in the correct place

    If there is an error creating the ec2 keypair, but we have created
    a user, we will lose track of the user id and be unable to delete

    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.
