Missing examples for v1alpha2 iothub resources

[ytsarev]

What happened?

We have following v1alpha2 iouthub resources configured under devices API group:

grep AddResource config/devices/config.go
	p.AddResourceConfigurator("azurerm_iothub", func(r *config.Resource) {
	p.AddResourceConfigurator("azurerm_iothub_consumer_group", func(r *config.Resource) {
	p.AddResourceConfigurator("azurerm_iothub_dps", func(r *config.Resource) {
	p.AddResourceConfigurator("azurerm_iothub_dps_certificate", func(r *config.Resource) {
	p.AddResourceConfigurator("azurerm_iothub_dps_shared_access_policy", func(r *config.Resource) {
	p.AddResourceConfigurator("azurerm_iothub_shared_access_policy", func(r *config.Resource) {
	p.AddResourceConfigurator("azurerm_iothub_endpoint_storage_container", func(r *config.Resource) {
	p.AddResourceConfigurator("azurerm_iothub_fallback_route", func(r *config.Resource) {

At the same time we have a minimal number of examples for them:

ls -1 examples/devices
iothub.yaml
iothubendpointstoragecontainer.yaml
iothubfallbackroute.yaml

We need to create missing examples for the configured resources
