This implements a stream cleanup when using portforwardings. Before
applying this patch, the streams []httpstream.Stream within
`spdy/connection.go` would fill-up for each streaming request. This
could result in heavy memory usage. Now we use the stream identifier to
keep track of them and finally remove them again once they're no longer
needed.

Based on the comments in this file, it seems like these import
restrictions were originally meant for the kubelet CRI streaming
package. This commit moves the import restrictions to
pkg/kubelet/cri/streaming so that pkg/kubelet/cri can import internal
packages like pkg/probe/exec
