Get-AzureRmSqlServer cmdlet - Should provide an "Client IP Address" property.

### Description

Not getting the **_Azure SQL Client IP_** in PowerShell its been bothering me since the Azure Classics, and it still an issue in the AzureRM Sql cmdlets.

I just can't find this information. It force me to use the Azure Portal disrupting my script automation steps.

Of course, If there's a cmdlet that can provide me this information, then let me know. I have searched on "How to get the AzureRM SQL Client IP Address?", but the only place I found it is in the Azure portal.


I don't understand! If the portal has the ability to "**_Add Client Id_**" to the Firewall Rule, then why not make available in the New-AzureRmSqlServerFirewallRule Cmdlet.



It will work if I have an ClientIpAddress property accessible at least in the **Get-AzureRmSqlServer** cmdlet.
This will make it much easier to create an Azure Sql Server and then add the firewall rule using the "_**ClientIpAddress**_" given to the new SqlServer


### Script/Steps for Reproduction

The "**_Client IP Address_**" should be included after creating the Azure SQL asset:
```powershell
## - Providing existing AzureRmSqlServer information:
Get-AzureRmSqlServer -ResourceGroupName azResourceEast01

## - Providing existing AzureRmSqlServer Firewall information:
Get-AzureRmSqlServerFirewallRule -ServerName azsqls01 -ResourceGroupName azResourceEast01
```
