Loadbalanced client src ip preservation enters beta
Sounds like we're going to try out the proposal (https://github.com/kubernetes/kubernetes/issues/30819#issuecomment-249877334) for annotations -> fields on just one feature in 1.5 (scheduler). Or do we want to just convert to fields right now?

Split conversion and defaulting
Separate conversion and defaulting. Defaulting occurs mixed with conversion today - change the server so that the `VersioningCodec` performs defaulting on the external type during decoding.
* Add a new method to `Scheme` - `func (*runtime.Scheme) Default(runtime.Object)` - that takes an object and performs defaulting.
* Call `Default` during decoding and at static initialization time
* Use the new `defaulter-gen` to generate top level object defaulters (`v1.Pod`) at build time for any type that needs to perform defaulting.
* Add tests and alter the existing code to adapt as necessary
* Fix a few bugs in conversions that depended on defaulting behavior
---
Step 1 of decoupling conversion and defaulting. The generator will assist in creating top level defaulters that in a single method invoke all nested defaulters, preventing the need to recurse via reflection or conversion. These top level defaulters will be registered in the scheme and invoked instead of the nested recursion path. This will set the stage for a future generator, capable of creating defaulters from embedded struct tags on external types. However, we must gradually switch these over.
The immediate goal here is to split defaulting and conversion so that the unsafe convertor can be used to maximum potential (we would be able to use direct memory conversion for any identical nested struct, even those that must be defaulted).
The generator uses `k8s:defaulter-gen=TypeMeta` on most public packages to flag any top level type that has defaulters to get a `SetObjectDefaults_NAME` function created (types that don't have defaulters won't have functions). This also creates a `RegisterDefaults` method that applies a default to an interface{} and returns true if the object was handled. Existing defaults are left as is.
Add a test to verify old and new path generate the same outcomes. Defaulter will move to gengo before this is merged, and subsequent PRs will remove defaulting during conversion and have the VersioningCodec apply defaults.
Most normal codec use should perform defaulting. DirectCodecs should not
perform defaulting. Update the defaulting_test to fuzz the list of known
defaulters. Use the new versioning.NewDefaultingCodec() method.

Add PSP support for seccomp profiles
Seccomp support for PSP. There are still a couple of TODOs that need to be fixed but this is passing tests.
One thing of note, since seccomp is all being stored in annotations right now it breaks some of the assumptions we've stated for the provider in terms of mutating the passed in pod. I've put big warning comments around the pieces that do that to make sure it's clear and covered the rollback in admission if the policy fails to validate.

Add PVC storage to LimitRange
This PR adds the ability to add a LimitRange to a namespace that enforces min/max on `pvc.Spec.Resources.Requests["storage"]`.
@derekwaynecarr @abhgupta @kubernetes/sig-storage
Examples forthcoming.
```release-note
pvc.Spec.Resources.Requests min and max can be enforced with a LimitRange of type "PersistentVolumeClaim" in the namespace

Match GroupVersionKind against specific version
Currently when multiple GVK match a specific kind in `KindForGroupVersionKinds` only the first will be matched, which not necessarily will be the correct one. I'm proposing to extend this to pick the best match, instead.
Here's my problematic use-case, of course it involves ScheduledJobs 😉:
I have a `GroupVersions` with `batch/v1` and `batch/v2alpha1` in that order. I'm calling `KindForGroupVersionKinds` with kind `batch/v2alpha1 ScheduledJob` and that currently results this matching first `GroupVersion`, instead of picking more concrete one. There's a [clear description](ee77d4e6ca/pkg/api/unversioned/group_version.go (L183)) why it is on single `GroupVersion`, but `GroupVersions` should pick this more carefully.
@deads2k this is your baby, wdyt?
Contination of #1111
I tried to keep this PR down to just a simple search-n-replace to keep
things simple. I may have gone too far in some spots but its easy to
roll those back if needed.
I avoided renaming `contrib/mesos/pkg/minion` because there's already
a `contrib/mesos/pkg/node` dir and fixing that will require a bit of work
due to a circular import chain that pops up. So I'm saving that for a
follow-on PR.
I rolled back some of this from a previous commit because it just got
to big/messy. Will follow up with additional PRs

Dynamic provisioning for flocker volume plugin
Refactor flocker volume plugin
* [x] Support provisioning beta (#29006)
* [x] Support deletion
* [x] Use bind mounts instead of /flocker in containers
* [x] support ownership management or SELinux relabeling.
* [x] adds volume specification via datasetUUID (this is guranted to be unique)
I based my refactor work to replicate pretty much GCE-PD behaviour
