Update: enable OS_DEBUG (terraform-provider-openstack#1246)

* Update: enable debug logging in the provider

 - when TF_LOG is debug/trace (and OS_DEBUG is not set)
 - enable this by default (person probably wants it)

Resolves: terraform-provider-openstack#1203

* Chore: update github.com/gophercloud/utils
