Use netexec container in http lifecycle hook test.
Fixes https://github.com/kubernetes/kubernetes/issues/33636.
The original test is using `"echo -e \"HTTP/1.1 200 OK\n\" | nc -l -p 1234` as a simple http server.
However, it seems that this is not very reliable, which may response before golang thinks it should.
So we get the error:
```
I1106 06:14:13.325397 2096 logs.go:41] Unsolicited response received on idle HTTP channel starting with "HTTP/1.1 200 OK\n\n"; err=<nil>
```
This PR changes the test to use the `netexec` container which is a simple http server written by golang and used in many of our networking e2e test. It should be more reliable.
Mark 1.5 since this is fixing a 1.5 release blocking issue. Mark P0 to match the original issue.

Node E2E: Update ubuntu image to e2e-node-ubuntu-trusty-docker10-v2-image.
@sjenning Hopefully this will unblock https://github.com/kubernetes/kubernetes/pull/32577.
I built a new ubuntu trusty image with docker 10 - `e2e-node-ubuntu-trusty-docker10-v2-image`. The kernel version of the new ubuntu image is `4.4.0-47-generic`.

Change stickyMaxAge from seconds to minutes, fixes issue #35677
**What this PR does / why we need it**: Increases the service sessionAfinity time from 180 seconds to 180 minutes for proxy mode iptables which was a bug introduced in a refactor.
**Which issue this PR fixes**: fixes#35677
**Special notes for your reviewer**:
**Release note**:
``` release-note
Fixed wrong service sessionAffinity stickiness time from 180 sec to 180 minutes in proxy mode iptables.
```
Since there is no test for the sessionAffinity feature at the moment I wanted to create one but I don't know how.

HA master, fixed replica name when creating load balancer.
HA master, fixed replica name when creating load balancer. Was broken when replica

Fixed e2e tests for HA master.
Set of fixes that allows HA master e2e tests to pass for removal/addition master replicas.
The summary of changes:
- fixed host name in etcd certs,
- added cluster validation after kube-down,
- fixed the number of master replicas in cluster validation,
- made MULTIZONE=true required for HA master deployments, ensured we correctly handle MULTIZONE=true when user wants to create HA master but not kubelets in multiple zones,
- extended verification of master replicas in HA master e2e tests.

Add more logging around Pod deletion
After this PR we'll have at least V(2) level log near all Pod deletions.

Check sysfs Type instead of Device
Some distribution uses "none" device to mount "sysfs" type, so kube-proxy needs to list mount points and check "types" instead of "device".
fixes#37183

Change sysfs mountpoint tests from Device to Type to be able to find sysfs mountpoint on "none" device

Test flake: ignore dig failure; wait until timeout
The intent of this test was to continue trying until the timeout has
been reached. The extra assertion makes the test fail early when it
should not.

Update the timeout in CLOSE_WAIT e2e test
I see some test flakes due to the timeout being too strict,
updating to a larger value.
Adding tail -n 1, it looks like there may be leftover state for other
runs. We really only care about one of the CLOSE_WAIT entries.

Revert "Avoid hard-coding list of Node Conditions"
* we don't know how other API consumers are using node conditions (there was no prior expectation that the scheduler would block on custom conditions)
* not all conditions map directly to schedulability (e.g. `MemoryPressure`/`DiskPressure`)
* not all conditions use True to mean "unschedulable" (e.g. `Ready`)
This reverts commit 511b2ecaa8 to avoid breaking existing API users and to avoid constraining future uses of the node conditions API

Read all resources for finalization and gc, not just preferred
Fixes#31481.
Currently when starting namespace controller or garbage collector we only gather preferred version resources, which in case of multiple versions (you guessed it `batch/v2alpha1.CronJobs` again) isn't sufficient. This PR adds additional method which actually retrieves all resources from all versions and works on them.

[Federation][join-flags] Add flags for cluster context and secret names while joining clusters to federation.
Vast majority of cluster contexts are not RFC 1123 subdomains. Since
cluster and secret names for the API objects are derived from the
cluster context name, there is no way for users to join clusters
with such context names to federation, unless they modify the context
name in their kubeconfigs itself. That's a lot of inconvenience and
entirely goes against the goal and beats the purpose of the `kubefed`
tool. So we are providing these flags to allow users to override these
values.
Also, since users register their clusters with federation, it is makes
sense in terms of user experience to make the cluster name a positional
argument because that feels more natural. Also, specifying cluster name
in the join command as a mandatory positional argument make
`kubefed join` consistent with `kubefed unjoin`. This also means
`--cluster-context` is now made a flag and defaults to cluster name if
unspecified.
`--secret-name` also defaults to the cluster name if unspecified.
Fixes: Issue #35954
