Preserve query strings in HTTP probes instead of escaping them
Fixes a problem reported on Slack by devth.
```release-note
* Allow the use of query strings and URI fragments in HTTP probes
```
This might also preserve fragments, for those crazy enough to pass them.
I am using url.Parse() on the path in order to get path/query/fragment
and also deliberately avoiding the addition of more fields to the API.

GCI: add support for network plugin
I had run e2e against a cluster with both master and nodes on GCI a couple of times. The PR auto tests will cover the hybrid cluster with just master on GCI.

Resource quantity must support leading and trailing whitespace in JSON for back-compat
For backwards compatibility reasons, we must continue to support leading or trailing whitespace on Quantity values when deserialized from JSON. We must also support numbers serialized into yaml (`cpu: 1`) and JSON (`"cpu": 1`)

Move quota usage testing for loadbalancers into unit tests
Fixes https://github.com/kubernetes/kubernetes/issues/26319
* moved testing for node port and load balancer usage in quota to unit tests
* remove node port and node port -> loadbalancer service testing out of e2e
* covered already in replenishment_controller_test scenario
Given the time it takes to even allocate a load balancer, it seems better to test that outside of this test case to avoid unnecessary flakes.

Flake 26210: decouple explicit access from port 80
Flake #26210 only happens for port 80. To decouple the possible causes, all
tests with explicit port 80 are moved to port 1080 (these were 80% of the flakes).
The urls without a specified port (which map to port 80 though) are left untouched.
If port 1080 does not show up as flake now, there is really a connection to the
actual port number.

Reduce huge amount of logs in large cluster tests
When running tests in 2000-node clusters, I got more than 100.000 lines like this:
```
Jun 8 01:03:11.850: INFO: Condition NetworkUnavailable of node gke-gke-large-cluster-default-pool-1-03ee5a12-knrw is true instead of false. Reason: NoRouteCreated, message: Node created w ithout a route
```
that doesn't give much value.
This is PR is reducing the number of logs.

GCI: fix the issue #26379
This PR deletes docker0 explicitly to fix the issue. In some cases, coexistence of docker0 and cbr0 make troubles in GCI-based cluster instances.
I verified it in GKE. With the fix, fluentd-gcp pod shows no error. "curl google.com" can work inside a pod. Mark it as P0 to match the issue priority.

DeepCopy should generate types within k8s.io/kubernetes
Take an incremental step to control which types get DeepCopy generated.
Fixes#26036, #24667
@thockin @wojtek-t @lavalamp
Also includes other improvements:
- Makefile rule to run tests against remote instance using existing host or image
- Makefile will reuse an instance created from an image if it was not torn down
- Runner starts gce instances in parallel with building source
- Runner uses instance ip instead of hostname so that it doesn't need to resolve
- Runner supports cleaning up files and processes on an instance without stopping / deleting it
- Runner runs tests using `ginkgo` binary to support running tests in parallel
