Adding option to set the federation api server port if nodeport is set

**What this PR does / why we need it**: Kubefed will deploy the respected services and then it will do a health check. Prior to this patch if the user selects the nodeport a random port is opened. In environments where firewalls are in place this random port selection will cause the health check to fail. With this patch we enable users to designate a specific port, after for example opening it on their firewall.    

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #46021
