- adjust ports to int32
- CRI flows the websocket ports as query params
- Do not validate ports since the protocol is unknown
SPDY flows the ports as headers and websockets uses query params
- Only flow query params if there is at least one port query param

move client/record
An attempt at moving client/record to client-go. It's proving very stubborn and needs a lot manual intervention and near as I can tell, no one actually gets any benefit from the sink and source complexity it adds.

Kubelet: add image ref to ImageService interfaces
This PR adds image ref (digest or ID, depending on runtime) to PullImage result, and pass image ref in CreateContainer instead of image name. It also
* Adds image ref to CRI's PullImageResponse
* Updates related image puller
* Updates related testing utilities
~~One remaining issue is: it breaks some e2e tests because they [checks image repoTags](https://github.com/kubernetes/kubernetes/blob/master/test/e2e/framework/util.go#L1941) while docker always returns digest in this PR. Should we update e2e test or continue to return repoTags in `containerStatuses.image`?~~
Fixes#38833.

Add 'privileged' to sandbox to indicate if any container might be privileged in it, document privileged
Right now, the privileged flag is this magic thing which does "whatever Docker does". This documents it to make it a little less magic.
In addition, due to how rkt uses `systemd-nspawn` as an outer layer of isolation in creating the sandbox, it's helpful to know beforehand whether the pod will be privileged so additional security options can be applied earlier / applied at all.
I suspect the same indication will be useful for userns since userns should also occur at the pod layer, but it's possible that will be a separate/additional field.

Use indirect streaming path for remote CRI shim
Last step for https://github.com/kubernetes/kubernetes/issues/29579
- Wire through the remote indirect streaming methods in the docker remote shim
- Add the docker streaming server as a handler at `<node>:10250/cri/{exec,attach,portforward}`
- Disable legacy streaming for dockershim
Note: This requires PR https://github.com/kubernetes/kubernetes/pull/34987 to work.
Tested manually on an E2E cluster.

This allows us to interrupt/kill the executed command if it exceeds the
timeout (not implemented by this commit).
Set timeout in Exec probes. HTTPGet and TCPSocket probes respect the
timeout, while Exec probes used to ignore it.
Add e2e test for exec probe with timeout. However, the test is skipped
while the default exec handler doesn't support timeouts.
