hooks: Add hook for collecting information about triggered containers and/or nested containers

[dougsland]

We should have a schema to log information about the system, any container triggered AND/OR nested container included, such informations are:

cat /etc/fstab
free -hg
df -h
etc.

Hooks are a good way to handle that, create a function logic to be called before/after/during the execution of the script.
A good script to start using this hook would be: https://github.com/containers/engine-stressor/blob/main/memory-exhaustion/memory-exhaustion
