Add support for oci-hooks to libkpod

Browse source 
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.
