This commit adds a StateRefresh func for volume attachments. Mostly
this is to add a buffer of time between the request and the return
of the attachment to give time for the volume to become attached,
however, in some cases the refresh function could work as specified.
Docs have also been updated to reflect that a device could be specified,
but to use with caution.
* provider/openstack: Detect Region for Importing Resources
This commit changes the way the OpenStack region is detected and set.
Any time a region is required, the region attribute will first be
checked. Next, the OS_REGION_NAME environment variable will be checked.
While schema.EnvDefaultFunc handles this same situation, it is not
applicable when importing resources.
* provider/openstack: No longer ignore region in importing tests
* provider/openstack: Network and Subnet Import Fixes
This commit fixes the OpenStack Network and Subnet resources so that
importing of those resources is successful.
This commit adds the openstack_compute_volume_attach_v2 resource. This
resource enables a volume to be attached to an instance by using the
OpenStack Compute (Nova) v2 volumeattach API.
