Generate OpenAPI definition for inlined types
Currently OpenAPI definition generator ignores any type's member with an empty json name tag. However, most (if not all) of these types also have "inline" json tag. That means we should inline their members into parent type's OpenAPI definition instead of ignoring them. This resulted in many types missing common parameters such as "Name". It look something serious to me for OpenAPI spec and I suggest we merge and cherry-pick this into 1.5 release branch as soon as possible.

conversion-gen: add --skip-unsafe flag
We should expose the SkipUnsafe option, for legacy compatability, so
that conversion-go can be used in other projects, and for platforms
where unsafe is not available.
Make unsafe code generation the default though, and have the help text
hint that the resulting code is sub-optimal.

Add generated informers
Add informer-gen and the informers it generates. We'll do follow-up PRs to convert everything currently using the hand-written informers to the generated ones.
TODO:
- [x] switch to `GroupVersionResource`

Add tooling to generate listers
Add lister-gen tool to auto-generate listers. So far this PR only demonstrates replacing the manually-written `StoreToLimitRangeLister` with the generated `LimitRangeLister`, as it's a small and easy swap.

Given an object that wishes to have a top level defaulter, traverse the
object looking for nested fields that have defaulters and generate a
single function for that type that invokes all defaulters. The function
will have the name `SetObjectDefaults_NAME`.
Types use `// +k8s:defaulter-gen=true` to indicate they wish a defaulter
generated. If a function already exists with the desired name
`SetObjectDefaults_NAME` then no generation will occur. At a package
level, authors can bulk select the types to generate by setting the
value of the comment to the name of a field - all objects with that
field name without `// +k8s:defaulter-gen=false` defined on the type
will get a defaulter.
Because the defaulting behavior from conversions happens recursively,
all defaulters are expected to be invoked. We call these defaulters
"non-covering" (other defaulters may be invoked beneath them). The
defaulters we generate, by comparison, are "covering" - no nested
defaulters should be invoked. To distinguish between these two types, we
introduce the `// +k8s:defaulter-gen=covers` comment on a defaulter
function which will instruct the generator that the function should
terminate recursion.
This sets the stage for future defaulter generation from comments by
subsuming our existing generators

Speed up dockerized builds
This PR speeds up dockerized builds. First, we make sure that we are as incremental as possible. The bigger change is that now we use rsync to move sources into the container and get data back out.
To do yet:
* [x] Add a random password to rsync. This is 128bit MD4, but it is better than nothing.
* [x] Lock down rsync to only come from the host.
* [x] Deal with remote docker engines -- this should be necessary for docker-machine on the mac.
* [x] Allow users to specify the port for the rsync daemon. Perhaps randomize this or let docker pick an ephemeral port and detect the port?
* [x] Copy back generated files so that users can check them in. This is done for `zz_generated.*` files generated by `make generated_files`
* [x] This should include generated proto files so that we can remove the hack-o-rama that is `hack/hack/update-*-dockerized.sh`
* [x] Start "versioning" the build container and the data container so that the CI system doesn't have to be manually kicked.
* [x] Get some benchmarks to qualify how much faster.
This replaces #28518 and is related to #30600.

make-generated-{protobuf,runtime}.sh was doing some really nasty stuff with how
the build container was managed in order to copy results out. Since we have
more flexibility to grab results out of the build container, we can now avoid
all of this. Ideally we wouldn't have `hack` calling `build` at all, but we
aren't there yet.

Autoconvert cleanups
A few accumulated cleanups to conversion, and then a big change. Please review commit-by-commit. Verified by nuking all generated files and comparing the new results.
cc @lavalamp
Previously we refused to emit 'autoConvert_*' functions if any field was not
convertible. The way around this was to write manual Conversion functions, but
to do so safely you must handle every fields. Huge opportunity for errors.
This PR cleans up the filtering such that it only operates on types that should
be converted (remove a lot of code) and tracks when fields are skipped. In
that case, it emits an 'autoConvert' function but not a public 'Convert'
function. If there is no manual function, the compile will fail.
This also means that manual conversion functions can call autoConvert functions
and then "patch up" what they need.
