Add a IpConfiguration in an ApplicationSecurityGroup

I have searched very much but I haven't be able to find a way to add an IpConfiguration inside an ApplicationSecurityGroup. It is possible from Azure-cli with the following command:

`az network nic ip-config update -g core-services --nic-name vm1-net1923 --application-security-groups core-asg`

And I tried the same from Java SDK:

`azure.networkInterfaces().getById("nicId").update().updateIPConfiguration("configId")`

But there not option for ApplicationSecuritygroups.

Start with the azure.networkInterfaces().getById("nicId").update().updateIPConfiguration("configId") entry point and compare its available options with the Azure CLI command. Trace how IpConfiguration updates are represented, then verify that ApplicationSecurityGroup association can be requested and persisted through the Java SDK.
