return keychain, tempdirectory
This function creates a temporary Mac keychain that we can use to work with
    credentials. This keychain uses a one-time password and a temporary file to
    store the data. We expect to have one keychain per socket. The returned
    SecKeychainRef must be freed by the caller, including calling
    SecKeychainDelete.

    Returns a tuple of the SecKeychainRef and the path to the temporary
    directory that contains it.
