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.
```
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.

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.

GCE: Use existing subnetwork of ILB forwarding rule
Fixes#57860
**Test Cases**:
Clusters using auto network with existence of a manual subnet in same region.
- [x] Upgrade 1.7 cluster with existing ILBs to latest. Confirm existing ILBs still are synced.
Version 1.7 does not attempt to fill in the subnetwork, so the forwarding rule was created with the correct subnetwork.
- [x] Upgrade 1.8 cluster with existing ILBs to latest. Confirm existing ILBs (using wrong subnet) still are synced.
- [x] Latest version creates ILBs using the correct subnet.
Clusters with manual subnets have always and will continue to use the subnet specified in gce.conf.
- [x] Upgrade 1.8 cluster with existing ILBs to latest. Confirm existing ILBs (using manual subnet) still are synced.
Clusters with legacy networks have always and will continue to use an empty subnet.
- [x] Upgrade 1.8 cluster with existing ILBs to latest. Confirm existing ILBs (using legacy network) still are synced.

```
It's interesting that those service does not need loadbalancer, and caller is just checking whether one loadbalancer exists.
009701f181/pkg/controller/service/service_controller.go (L287)
And in we can see when err is not nil, it will not check exists value. Thus we should not return error when exists=false.
This was changed in:
edfb2ad552 (diff-c901394068476b4ccb003a6c6efad57cR63)
The PR removes the error when exists=false.
