[RFE] Add docker container information

[e-minguez]

You can use this as example:

printf "\ncontainers:\n"
docker ps --format 'table {{.Names}}\t{{.Status}}' | tr '[A-Z]' '[a-z]' | column -ts $',' | sed -e 's/^/  /'

Thanks!

I just added a docker script. You can test it and check if everything works.
