If LBaaSV2 member creation/deletion is attempted while LB resource is
busy (for example it's in PENDING_UPDATE state), Neutron will return 500
error. Currently This being caught by type assertion to
ErrUnexpectedResponseCode, however error 500 has a dedicated type
ErrDefault500, which makes the current type assertion to miss it and
eventually the error slips out through the check. This patch
changes the type assertion to explicitly check for ErrDefault500.
Also similar check has been added when member is deleted.
* 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.
