Allow to set poll interval to OSC stack create

In certain scenarios the default poll interval of 5s used by
`openstack stack create --wait` command is too short.

Setting the poll interval was supported in heat CLI with
`heat stack-create --poll N` but is missing in OSC plugin.

This patch adds an optional argument `--poll N` (N defaults to 5) to the
`openstack stack create` command.
