Add cinder create --poll

Usage: It adds an optional argument --poll to the cinder
create command which waits while the creation of the volume
is completed and the volume goes to available state. In case
there is an error in volume creation, it throws an error message
and exits with a non zero status. The error message printed here
is the async error message in case it generates one.
