    Switch from deprecated isotime

    oslo_utils.timeutils.isotime() is deprecated as of 1.6 so we need
    to stop using it.

    The deprecation message says to use datetime.datetime.isoformat()
    instead, but the format of the string generated by isoformat isn't
    the same as the format of the string generated by isotime. The string
    is used in tokens and other public APIs and we can't change it
    without potentially breaking clients.

    So the workaround is to copy the current implementation from
    oslo_utils.timeutils.isotime() to keystone.common.utils.isotime().
