Description of problem:
kube-controller-manager ignores --master argument
Version-Release number of selected component (if applicable):
[root@f23 kubernetes]# rpm -qa | grep kubernetes sort
kubernetes-1.2.0-0.13.alpha6.gitf0cd09a.fc23.x86_64
kubernetes-client-1.2.0-0.13.alpha6.gitf0cd09a.fc23.x86_64
kubernetes-master-1.2.0-0.13.alpha6.gitf0cd09a.fc23.x86_64
kubernetes-node-1.2.0-0.13.alpha6.gitf0cd09a.fc23.x86_64
How reproducible:
Always
Steps to Reproduce:
After setting up system like you normally would do (create cert etc..) observe
the kube-controller manager service ignores the '--master' arg on the command
line.
You can repro with this command:
```
/usr/bin/kube-controller-manager --logtostderr=true --v=0
--master=http://127.0.0.1:8080
--service_account_private_key_file=/etc/pki/kube-apiserver/serviceaccount.key
```
I set up my systems using the lines in this ansible playbook:
https://github.com/dustymabe/vagrantdirs/blob/master/f23/playbook.yml#L62
Actual results:
The following is the message you receive. Note the "nor --master was specified"
log message, which indicates it didn't recognize the
--master=http://127.0.0.1:8080 argument we provided:
```
[root@f23 kubernetes]# /usr/bin/kube-controller-manager --logtostderr=true
--v=0 --master=http://127.0.0.1:8080
--service_account_private_key_file=/etc/pki/kube-apiserver/serviceaccount.key

```
As a result we see this when trying to create a pod:
```
[root@f23 ~]# kubectl create -f /tmp/busybox.yaml
Error from server: error when creating "/tmp/busybox.yaml": pods "busybox" is
forbidden: no API token found for service account default/default, retry after
the token is automatically created and added to the service account
```
