Terraform provider ProfitBricks - Data Sources (#11520)

* Terraform ProfitBricks Builder

* make fmt

* Merge remote-tracking branch 'upstream/master' into terraform-provider-profitbricks

# Conflicts:
#	command/internal_plugin_list.go

* Addressing PR remarks

* Removed importers

* Added ProfitBricks Data Sources

* Added documentation

* Updated to REST v3:
- nat parameter for Nics
- availabilityZone for Volumes

Minor code clean up

* Minor code clean up

* Fixed typo in volume documentation

* make fmt

* Addressing requested changes

* Added a step in load balancer tests in CheckDestroy where we are making sure that the test doesn't leave dangling resources in ProfitBricks

* Changed expected image name

* Fixed data center test
