able to renewsliver expiration beyond slice expiration

[lnevers@bbn.com]

In a scenario where the slice expiration is set to "2013-03-26 00:00:00" it is possible to renew a sliver to a date beyond the slice expiration, (ex. Thu Mar 28 00:00:00 UTC 2013)

The slice expiration time:

This is really same as 152. We don't look at SA cred document for expiration date.

It just needs to be looked at for both create and extend.
