Remove needless env var in OpenStack provider
**What this PR does / why we need it**:
If we use openstack provider to set up k8s cluster using kube-up script,
`TENANT_ID` environment variable is needed.
But to configure `TENANT_ID` is very annoying because this value is not static by each env.
This patch uses `TENANT_NAME` instead of `TENANT_ID`

Since `TENANT_NAME` is unique if we use keystone v2 api,
so `TENANT_ID` is not needed if `TENANT_NAME` is provided
to configure OpenStack provider.
And also to set `TENANT_ID` is annoying to develop, because
`TENANT_ID` is not static by each environment.
This patch remove dependency of `TENANT_ID` and simply use
`TENANT_NAME`.

`FIXED_NETWORK_CIDR` environment variable is mandatory by
openstack-heat kubernetes provider, but it's missing as
default value. Adding this environment variable is helpful
to build kubernetes cluster using openstack-heat provider.
So this patch adds it.
The admission controller adds a default class to PVCs that do not require any
specific class. This way, users (=PVC authors) do not need to care about
storage classes, administrator can configure a default one and all these PVCs
that do not care about class will get the default one.
Fixed the order of fields for basic_auth.
This provider still needs to leverage common.sh for generating proper credentials though.
Also documented a pattern for how to get the SWIFT_SERVER_URL automatically
