dd status=none does not exist on macOS
**What this PR does / why we need it**:
When running cluster/kubectl.sh on macOS 10.13.6, the use of the
`status=none` operand leads to `dd: unknown operand status` being
printed out as an error message. Redirecting to /dev/null does
the same thing, supressing transfer status.

Exit gce kube-up.sh early if openssl is LibreSSL
**What this PR does / why we need it**:
macOS has an openssl binary, but it's actually LibreSSL, which doesn't play well with the easyrsa script that cluster/gce/util.sh uses to generate certs
Instead of waiting until we generate certs to discover easyrsa doesn't work, consider openssl a prereq for gce, and include a check for the version string starting with OpenSSL
Also, mirror kube-up.sh's "... calling" output in kube-down.sh

remove incomplete check of ipvs modules in hack/local-up-cluster.sh
**What this PR does / why we need it**:
Currently `hack/local-up-cluster.sh` executes `sudo modprobe -a ip_vs ip_vs_rr ip_vs_wrr ip_vs_sh nf_conntrack_ipv4` to check whether the ipvs required modules exist, which leaves out the scenario https://github.com/kubernetes/kubernetes/issues/63801 mentioned.
Since `func CanUseIPVSProxier` in `pkg/proxy/ipvs/proxier.go` covers all scenarios, maybe we should just remove this part instead of adding codes.

Simplify device manager: make endpoint stateless
While reviewing devicemanager code, found the caching layer on endpoint is redundant.
Here are the 3 related objects in picture:
**devicemanager <-> endpoint <-> plugin**
plugin is the source of truth for devices and device health status.
devicemanager maintain healthyDevices, unhealthyDevices, allocatedDevices based on updates
from plugin.
So there is no point for endpoint to cache devices, this patch is removing the cache layer,
endpoint becomes stateless, which i believe should be the case (but i do welcome review
if i missed something here).
also removing the Manager.Devices() since i didn't find any caller of this other than test.
if we need to get all devices from manager in future, it just need to return healthyDevices + unhealthyDevices, so don't have to call endpoint after all.
This patch makes code more readable, data model been simplified.
**What this PR does / why we need it**:
this patch simplify the device manager code, make it more maintainable.
**Which issue(s) this PR fixes** *:
this is a refactor of device manager code
**Special notes for your reviewer**:
will need to rebase the code if #58755 get checked-in first.

In our e2e test suite we have use an image "gcr.io/kubernetes-e2e-test-images:k8s-aggregator-sample-apiserver:1.7v2". We need a way to build a fresh image that can we can use instead of that one.

Percent-encode illegal characters in user.Info.Extra keys
This percent-encodes characters in `X-Remote-Extra-` and `Impersonate-Extra-` keys which aren't valid for header names per [RFC 7230](https://tools.ietf.org/html/rfc7230#section-3.2.6) (plus "%" to avoid breaking keys which contain them). The API server then blindly unescapes these keys.
Reviewer note:
Old clients sending keys which were `%`-escaped by the user will have their values unescaped by new API servers. New clients sending keys containing illegal characters (or "%") to old API servers will not have their values unescaped. This version skew incompatibility is a compromise discussed in #63682.
Fixes#63682
PTAL @mikedanese
**Release note**:
```release-note
action required: the API server and client-go libraries have been fixed to support additional non-alpha-numeric characters in UserInfo "extra" data keys. Both should be updated in order to properly support extra data containing "/" characters or other characters disallowed in HTTP headers.

Add dnsmasq to test/images/dnsutils
**What this PR does / why we need it**:
We currently use k8s.gcr.io/k8s-dns-dnsmasq:1.14.5 in the
dns_common.go file. Looking deeper, all we need is "/usr/sbin/dnsmasq"
from that image. So just enhance the dnsutils image and throw dnsmasq
into it. This makes it easier as the dockerfiles/sidecars etc in
kubernetes/dns is not really needed. Note that a previous attempt to add
manifests to that repo fell through in PR 30 in that repo (since we were
moving to coredns).
