The commit I34b12b96de3ea21beaf935ed8a9f6bae2fe0d0bc and
Ib384ae8130dcc6cbd47a837d11ca171ce02ef29e introduced the
deprecated oslo_utils.timeutils.isotime() is deprecated
as of 1.6.
The deprecation message says to use the 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 ec2api.api.ec2utils.
