Issue #1470 raises a regression in v1.8 of the Provider where it's no longer possible to set the private_ip_address field on azurerm_lb to a blank string. This PR extends the validate.IP4Address method to add an overload which allows for blank spaces.

On master the new test currently fails as an empty string isn't a valid IPv4 address:

$ acctests azurerm TestAccAzureRMLoadBalancer_emptyPrivateIP
=== RUN   TestAccAzureRMLoadBalancer_emptyPrivateIP
--- FAIL: TestAccAzureRMLoadBalancer_emptyPrivateIP (0.03s)
	testing.go:513: Step 0 error: config is invalid: azurerm_lb.test: "frontend_ip_configuration.0.private_ip_address" is not a valid IP4 address: ""
FAIL
FAIL	github.com/terraform-providers/terraform-provider-azurerm/azurerm	0.094s

On this branch - the tests pass as expected.

Fixes #1470
