This allows other packages and plugins to easily exec things without
racing with the reaper.
The reaper is mostly needed in the shim but can be removed in containerd
in favor of the `exec.Cmd` apis

This enables the grpc timing histograms via a config option as they are
metrics of high cardinality.
This is useful for perf testing and debugging but should not be the
default on production systems unless needed.
```toml
[metrics]
grpc_histogram = true
```

explicitly needed for it to be off.

This adds a config option to place the `containerd` daemon process into
a cgroup so that proper resource usage and accounting can be applied.
It defaults to not being place inside a cgroup and will create a new
cgroup if the `path` does not exist in the config or join an existing
`path` if it already exists.
```toml
[cgroup]
path = "/containerd"
```
