Fix booting from volume when using api v3

The current code in novaclient/base.py, class BootingManagerWithFind
do not take in account the differences required to boot an instance from
a volume in API v3. V3 expects UUID as volume id and also the source type
to be set.

Description is mandatory parameter when creating Security Group

As per the bug, description should not be a mandatory parameter
as it creates inconsistency with other opestack items which has
description as an optional parameter.

So in the fix, the description argument has been made optional.
The old command was:
nova secgroup-create <name> <description>
Now new command will be:
nova secgroup-create <name> [<description>]

Patch updated based on the comments received
