Update instructions of installing k8s VIM

The current `Kubernetes VIM installation` page has some
out-of-date instructions.

This patch replaces those out-of-date instructions with current
kubernetes manner, and fixes some other trivial mistakes
in the document.

.. note::
In Kubernetes data model, values contained under ``.data`` is encoded with
Base64 format, thus you must decode it with ``base64 --decode`` or
``base64 -d`` command to use it as a bearer token.
Before using this token, users have to apply administrator role to this token.
**Command:**
.. code-block:: console
password,user,uid,"group1,group2,group3"
$ kubectl create clusterrolebinding cluster-admin-binding \
--clusterrole cluster-admin --serviceaccount=default:default
In this example, the user belongs to group1, group2 and group3.

* Get Kubernetes server url
By default Kubernetes server listens on https://127.0.0.1:6443 and
https://{HOST_IP}:6443
By default Kubernetes API server listens on https://127.0.0.1:6443 and
https://{HOST_IP}:6443. Users can get this information through
``kubectl cluster-info`` command and try to access API server with
the bearer token described in the previous step.
.. code-block:: console
First, you have to confirm the API endpoint that your Kubernetes cluster exposes.
**Command:**
.. code-block:: console
$ kubectl cluster-info
**Result:**
$ curl http://localhost:8080/api/
{
"kind": "APIVersions",
"versions": [
"v1"
],
"serverAddressByClientCIDRs": [
{
"clientCIDR": "0.0.0.0/0",
"serverAddress": "192.168.11.110:6443"
}
]
}
.. code-block:: console
Kubernetes control plane is running at https://172.30.202.39:6443
To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
Then, you can confirm the API endpoint and your bearer token are available.
**Command:**
.. code-block:: console
$ curl -k https://172.30.202.39:6443/api/ -H "Authorization: Bearer $TOKEN"
**Result:**
.. code-block:: console
{
"kind": "APIVersions",
"versions": [
"v1"
],
"serverAddressByClientCIDRs": [
{
"clientCIDR": "0.0.0.0/0",
"serverAddress": "172.30.202.39:6443"
}
]
}
.. note::
Because SSL certificate used in Kubernetes API server is self-signed,
curl returns SSL certificate problem in the response. Users can use
``-k`` or ``--insecure`` option to ignore SSL certificate warnings, or
``--cacert <path/to/ssl_ca_cert_file>`` option to use ssl_ca_cert
in the verification of API server's SSL certificate.

In ``placement_attr``, there are four regions: 'default', 'kube-node-lease',
'kube-public' and 'kube-system', that map to ``namespace`` in Kubernetes environment.
After the successful installation of VIM, you can get VIM information as follows:
**Command:**
.. code-block:: console
$ openstack vim register --config-file vim_config.yaml vim-kubernetes
$ openstack vim list
$ openstack vim list
+--------------------------------------+----------------------------------+----------------+------------+------------+------------------------------------------------------------+-----------+
