Updating go-restful to generate "type":"object" instead of "type":"any" in swagger-spec (breaks kubectl 1.1)
Updating go-restful to include https://github.com/emicklei/go-restful/pull/270 (replacing type "any" by type "object". Ref https://github.com/swagger-api/swagger-codegen/issues/2347 on why we want to do that)

Mount hosts' /etc/hosts, /etc/resolv.conf, set host's hostname
when running the pod in the host's network.
Besides, do not set the DNS flags when running in host's network.
Previously, the service file's name is 'k8s_${POD_UID}.service',
which means we need to `systemctl daemon-reload` if the we replace
the content of the service file (e.g. pod is restarted).
However this makes the journal in the previous pod get disconnected.
This PR solves the issue by using the unique rkt uuid as the service
file's name. After the change, the service file's name will be:
'k8s_${rkt_uuid}.service'.

Client-gen: handle dotted group name, e.g., "authentication.k8s.io"
The client-gen used to assume the group name doesn't include dot, but it's not true, e.g., we have group `authentication.k8s.io`.
With this PR, Client-gen will use the full group name when creating directory (e.g., the client for the authentication group will be generated at pkg/client/clientset_generated/release_1_3/typed/`authentication.k8s.io`/v1/). However, because golang doesn't allow dot in variable/function names, so when the group name is used as part of variable/function name, client-gen extracts the part before the first dot (e.g., authentication).
This PR also changes the group name of the test group from `testgroup` to `testgroup.k8s.io` to verify if client-gen generates sane code.

Removing the explicit list of KUBE_API_VERSIONS will cause the apiserver
to enable all APIs by default. This change reduces the amount of script
hacking needed to add new API groups in the future.
If "a" is a bash array, then the syntax to append the contents of $line as a
new element to the array is a+=("$line"), not messages+=$line
Using the former syntax just seems to append to the first element, creating a
long string and thus losing newline information.
Fixing this allows us to drop some empty lines from invocations of
usage_from_stdin.
