Ability to specify OS_* variables for OpenStack configuration
**What this PR does / why we need it**:
When we convert the OpenStack cloud provider to run in an external
process, we should be able to use kubernetes Secrets capability to
inject the OS_* variables. This way we can specify the cloud
configuration as a configmap, specify secrets for the userid/password
information. The configmap can be mounted as a file. the secrets can
be made available as environment variables. the external controller
itself can run as a pod/daemonset.
For backward compat, we preload all the OS_* variables, if anything
is in the config file, then that overrides the environment variables.

**Special notes for your reviewer**:
The vsphere simulator recently moved from vmware/vic to govmomi, I had discussed the idea of introducing it for testing with vSphere Cloud Provider maintainers. These tests provide 90%+ coverage for vclib/datacenter.go, but we can expand further of course.

openstack: remove orphaned routes from terminated instances
**What this PR does / why we need it**:
At the moment the openstack cloudprovider only returns routes where the `NextHop` address points to an existing openstack instance. This is a problem when an instance is terminated before the corresponding node is removed from k8s. The existing route is not returned by the cloudprovider anymore and therefore never considered for deletion by the route controller. When the route's `DestinationCIDR` is reassigned to a new node the router ends up with two routes pointing to a different `NextHop` leading to broken networking.
This PR removes skipping routes pointing to unknown next hops when listing routes. This should cause [this conditional](93dc3763b0/pkg/controller/route/route_controller.go (L208)) in the route controller to succeed and have the route removed if the route controller [feels responsible](93dc3763b0/pkg/controller/route/route_controller.go (L206)).
```release-note
OpenStack cloudprovider: Ensure orphaned routes are removed.
```

Convert ComputerName to lower case
**What this PR does / why we need it**:
When instances count is greater than 10, azure will generate instance hostname with upper cases. But kubelet always converts hostname to lower case.
So azure cloud provider should also covert OsProfile.ComputerName to lower case.
