Kubelet can send cap add/drop ALL. Handle that in CRI-O as well.
Also, this PR is re-vendoring runtime-tools to fix capabilities add to
add caps to _all_ caps set **and** fix a shared memory issue (caps set
were initialized with the same slice, if one modifies one slice, it's
reflected on the other slices, the vendoring fixes this as well)

Add new directory /etc/crio/hooks.d, where packagers can drop a json config
file to specify a hook.
The json must specify a valid executable to run.
The json must also specify which stage(s) to run the hook:
prestart, poststart, poststop
The json must specify under which criteria the hook should be launched
If the container HasBindMounts
If the container cmd matches a list of regular expressions
If the containers annotations matches a list of regular expressions.
If any of these match the the hook will be launched.

kpod must parse the crio configuration file or the storage
is not set up correctly. By default it is not. We now read
/etc/crio/crio.conf in as the configuration file unless it is
overriden by the user and the global -c|--config switch.

Found out that during OpenShift testing, node was trying to remove
containers (probably in a bad state) and was failing the removal with
this kind of error:
E0828 13:19:46.082710 1235 kuberuntime_gc.go:127] Failed to remove
container
"e907f0f46b969e0dc83ca82c03ae7dd072cfe4155341e4521223d9fe3dec5afb": rpc

I believe it's ok to ignore this error as it may happen conmon will
fail early before exit file is written.

SetMaxThreads from runtime/debug in Golang is called to set max threads
value to 90% of /proc/sys/kernel/threads-max

Also, we distinguish between container and a pod infra
container in the exit monitor as pod infra containers
aren't stored in the main container index.

We calculate these values at container creation time and store
them in the container object as they are requested during container
status. This avoids re-calculation and speeds up container status.

We get notified of container exits by inotify so we already
have updated status of the container in memory state.

Containers running in kubernetes currently do not specify options
for mount propagation and whether to bind or rbind the mount point.
Since docker defaults to bind and rbind, we should match their
behavious, since this is what admins expect

This allows the container list API to return updated status

The storage library uses github.com/pkg/errors to wrap errors that it
returns from many of its functions, so when passing them to
os.IsNotExist() or comparing them to specific errors defined in the
storage library, unwrap them using errors.Cause().

Use unix.Prctl() instead of manually reimplementing it using
unix.RawSyscall. Also use unix.SECCOMP_MODE_FILTER instead of locally

The syscall package is locked down and the comment in [1] advises to
switch code to use the corresponding package from golang.org/x/sys. Do
so and replace usage of package syscall where possible (leave
syscall.SysProcAttr and syscall.Stat_t).
[1] https://github.com/golang/go/blob/master/src/syscall/syscall.go#L21-L24
This will also allow to get updates and fixes just by re-vendoring
golang.org/x/sys/unix instead of having to update to a new go version.
