Add a failsafe for etcd not returning a connection string
**What this PR does / why we need it**: Removing a kubernetes-master will fail as described on this issue: https://github.com/juju-solutions/bundle-canonical-kubernetes/issues/311
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes https://github.com/juju-solutions/bundle-canonical-kubernetes/issues/311
**Special notes for your reviewer**: This is a two liner defensive code. I am not totally sold on this patch. I might not be the right place to address the above issue. However, solving the problem on the etcd side and updating the interface scope to be unit (as suggested) seems much more involving.
**Release note**:
```
Fix error when removing juju kubernetes-master unit

fix systemd service file for custom args.
`KUBE_SCHEDULER_ARGS` and `KUBELET_ARGS` are used to custom args for scheduler or kubelet by users.
But if there are more than one params in `KUBELET_ARGS`, for example, if I set KUBELET_ARGS="--cgroups-per-qos=false --enforce-node-allocatable=", the kubelet will judge the `false --enforce-node-allocatable=` as the value of `cgroups-per-qos`. Because `${KUBELET_ARGS}` in kubelet.service will expands the variable into one word. And if I take `$KUBELET_ARGS` instead, kubelet will worker perfectly.
For more info, please click [EnvironmentFiles and support for /etc/sysconfig files](http://fedoraproject.org/wiki/Packaging:Systemd#EnvironmentFiles_and_support_for_.2Fetc.2Fsysconfig_files). This bug is reported by @huanxingyouyoutoo. And I make this PR for her to fix it.

Avoid redundant copying of tars during kube-up for gce if the same file already exists
**What this PR does / why we need it**:
Whenever I execute cluster/kube-up.sh it copies my tar files to google cloud, even if the files haven't changed. This PR checks to see whether the files already exist, and avoids uploading them again. These files are large and can take a long time to upload.
**Which issue this PR fixes**: fixes#46791
**Special notes for your reviewer**:
Here is the new output:
cluster/kube-up.sh
... Starting cluster in us-central1-b using provider gce
... calling verify-prereqs
... calling verify-kube-binaries
... calling kube-up
Project: PROJECT
Zone: us-central1-b
+++ Staging server tars to Google Storage: gs://kubernetes-staging-PROJECT/kubernetes-devel
+++ kubernetes-server-linux-amd64.tar.gz uploaded earlier, cloud and local file md5 match (md5 = 3a095kcf27267a71fe58f91f89fab1bc)
**Release note**:
```cluster/kube-up.sh on gce now avoids redundant copying of kubernetes tars if the local and cloud files' md5 hash match```

Remove limits from ip-masq-agent for now and disable ip-masq-agent in GCE
ip-masq-agent when issuing an iptables-save will read any configured iptables on the node. This means that the ip-masq-agent's memory requirements would grow with the number of iptables (i.e. services) on the node.
