    Drop AES functions and pycrypto dependency

    At some point IV parameter has been removed making these functions
    dangerous to use unless keys are unique on every message. Since the
    functions were added the original consumer has disappeared too. With
    no more users it's better to get rid of the incomplete encryption system
    entirely.

    These were the only functions using pycrypto module directly, so it was
    also removed from the dependency list.

Please find the attached test log from the Ubuntu Server Team's CI infrastructure. As part of the verification process for this bug, Nova has been deployed and configured across multiple nodes using precise-proposed as an installation source. After successful bring-up and configuration of the cluster, a number of exercises and smoke tests have be invoked to ensure the updated package did not introduce any regressions. A number of test iterations were carried out to catch any possible transient errors.
