Add docstring for create/update methods([a-f]*)

As we discussed on
http://lists.openstack.org/pipermail/openstack-dev/2015-July/068864.html
we need to write docstring for http POST/PUT methods.
This patch adds docstring for create/update methods of compute client
[a-f]*. In addition, this patch fixes some inconsistencies like "Creates"
is changed to "Create".
