proxy/iptables: don't sync proxy rules if services map didn't change
Build the service map in a separate testable function. Return that map instead of changing proxier.serviceMap directly. Use reflect.DeepEqual() to skip syncing proxy rules if nothing actually changed.

Check if path exists before performing unmount
This is part 3 of an effort to check if path exists before performing an unmount operation.
[Part 1](https://github.com/kubernetes/kubernetes/pull/38547) and [part 2](https://github.com/kubernetes/kubernetes/pull/39311) involved auditing the different volume plugins and refactoring their `TearDownAt()s` to use the common util function/or create one if absent.
The ideal way to do this change would involve refactoring of the `TearDownAt()s` of these plugins and make a common util function that checks path. (The plugins involved in this PR use someway of unmounting a bind mount and unmounting a global path, there is also refactoring needed to consolidate disk_manager of fc, rbd and iscsi). A non-goal part of this effort can also involve refactoring all the `SetupAt()s`
In the interest of time and considering other higher priority issues that I am caught up with, I am unable to give the time the refactoring needs. Hence I've made the minimum change that would give the desired output.
I am tracking the work pending in this issue: https://github.com/kubernetes/kubernetes/issues/39251

[CRI] Don't include user data in CRI streaming redirect URLs
Fixes: https://github.com/kubernetes/kubernetes/issues/36187
Avoid userdata in the redirect URLs by caching the {Exec,Attach,PortForward}Requests with a unique token. When the redirect URL is created, the token is substituted for the request params. When the streaming server receives the token request, the token is used to fetch the actual request parameters out of the cache.
For additional security, the token is generated using the secure random function, is single use (i.e. the first request with the token consumes it), and has a short expiration time.

delete unused variable in etcd_help_test.go

**Release note**: none
secifically we need to differentiate between wanting to run,
should run and should continue running. This is required to
support all taint effects and will improve reporting and end
user debuggability.
Instead of copying the map, like OnServicesUpdate() used to do and which
was copied into buildServiceMap() to preserve semantics while creating
testcases, start with a new empty map and do deletion checking later.
The API docs say:
// ServiceTypeExternalName means a service consists of only a reference to
// an external name that kubedns or equivalent will return as a CNAME
// record, with no exposing or proxying of any pods involved.
which implies that ExternalName services should be ignored for proxy
purposes.

The script does the import rewriting and gofmt. Then you do a build, codegen, bazel update, and it produces all the updates.
If we agree this is the correct approach. I'll create a verify script to make sure that no one messes with any files in the "dead" packages above.

Set PodStatus QOSClass field
This PR continues the work for https://github.com/kubernetes/kubernetes/pull/37968
It converts all local usage of the `qos` package class types to the new API level types (first commit) and sets the pod status QOSClass field in the at pod creation time on the API server in `PrepareForCreate` and in the kubelet in the pod status update path (second commit). This way the pod QOS class is set even if the pod isn't scheduled yet.

Allow rolebinding/clusterrolebinding with explicit bind permission check
Fixes https://github.com/kubernetes/kubernetes/issues/39176
Fixes https://github.com/kubernetes/kubernetes/issues/39258
Allows creating/updating a rolebinding/clusterrolebinding if the user has explicitly been granted permission to perform the "bind" verb against the referenced role/clusterrole (previously, they could only bind if they already had all the permissions in the referenced role via an RBAC role themselves)
```release-note
To create or update an RBAC RoleBinding or ClusterRoleBinding object, a user must:
1. Be authorized to make the create or update API request
2. Be allowed to bind the referenced role, either by already having all of the permissions contained in the referenced role, or by having the "bind" permission on the referenced role.

HPA Controller: Check for 0-sum request value
In certain conditions in which the set of metrics returned by Heapster
is completely disjoint from the set of pods returned by the API server,
we can have a request sum of zero, which can cause a panic (due to
division by zero). This checks for that condition.
Fixes#39680
**Release note**:
```release-note
Fixes an HPA-related panic due to division-by-zero.

remove API to server library dependency
A client library (which must include api types), should not depend on our server library. This duplicates one constant for conversion to avoid the link.
@smarterclayton @liggitt
The import-boss rule to keep us from forming these dependencies is non-trivial since some of the bits under /apis are server only (validation for instance).

Generate stable bindata output
fixes#30621
bindata generation produces spurious diffs when run with different go versions because gzip output is not stable between versions.
It also produces spurious diffs when invoked directly vs via make/go:generate.
This PR:
* adds data to bindata uncompressed (makes translation files human-readable, and the zip files were already compressed... for reference the file was 27.7 KB before, and 20.1 KB with this change)
* runs the generation from KUBE_ROOT, so it doesn't matter whether it is invoked directly or via go:generate
