Update Photon Controller cloud provider for authentication support
Resolve Issue: [#40755](https://github.com/kubernetes/kubernetes/issues/40755)
1. Update the configuration file for Photon Controller cloud provider
2. Only master nodes can communicate with Photon Controller endpoint
3. Enable support for authentication-enabled Photon Controller endpoint
4. Update NodeAddresses function for query from local node
New format of photon controller config file:
```
[Global]
target = https://[LOAD_BALANCER_IP]:443
project = [PROJECT ID]
overrideIP = true
vmID = [LOCAL VM ID]
authentication = true
```
This config file will be automatically created by Photon Controller cluster management.
If authentication file is set to true, then a pc_login_info file should be placed under /etc/kubernetes with username and password.
This file can be created by user directly.
Or the user can choose to use kubernetes secret and a handling pod to avoid directly login to master nodes. This usage will be available with Photon Controller 1.2.
This is a temporary solution before metadata service becomes available in Photon Controller.
