Instead of having several dialer implementations, leave only one in
`pkg/dialer` and call it from `pkg/ttrpcutil`, `runtime/v(1|2)/shim`
which had their own

When there is timeout or cancel for create container, killShim will fail
because of canceled context. The shim will be dangling and unmanageable.
Need to use new context to do cleanup.

Reized the I/O buffers to align with the size of the kernel buffers with fifos
and move the close aspect of the console to key off of the stdin closing.
Fixes#3738

When containerd-shim does reaper, the most processes are not init
process. Since json.Decode consumes more CPU resource, we should check
killall option for init process only.

This changes the shim's OOM score from a static max killable of -999 to
be +1 of the containerd daemon's score. This should allow the shim's to
be killed first in an OOM condition but leave the daemon alone for a bit
to help cleanup and manage the containers during this situation.

Closes#3286
This and a combination of a couple Docker changes are needed to fully
resolve the issue on the Docker side. However, this ensures that after
processes exit, we still leave some time for the I/O to fully flush
before closing. Without this timeout, the delete methods would block
forever.

Currently when we restart containerd it will load all tasks with shim
logs whether the `shim_debug` is set or not.

Open shim v2 log with the flag `O_RDWR` will cause the `Read()` block
forever even if the pipe has been closed on the shim side. Then the
`io.Copy()` would never return and lead to a fd leak.
Fix typo when closing shim v1 log which causes the `stdouLog` leak.
Update `numPipes` function in test case to get the opened FIFO
correctly.

1. kill shim in cleanupAfterDeadShim avoid shim leak
2. refactor cleanupAfterDeadShim, get pid from bundle
path instead of make pid as a parameter

* Rootfs dir is created during container creation not during bundle
creation
* Add support for v2
* UnmountAll is a no-op when the path to unmount (i.e. the rootfs dir)
does not exist or is invalid
