Fix for Azure loadbalancer tags. (#39963)

* Fix for Azure loadbalancer tags.

It was possible to add tags to an Azure loadbalancer, but the tags were never set in Azure.
This patch fixes that.

* Pass shippable tests

* azure_rm_loadbalancer_facts requires rg

Getting facts of all loadbalancers via azure_rm_loadbalancer_facts requires a resource group.
This fix adds the rg as parameter to the list() call.

* Revert changes in azure_rm_loadbalancer_facts

The changes belong to another pull request.
