Add docker commands to check if Fail2ban or CrowdSec containers are running

[alvarosaavedrau]

I have added Docker container commands to check if the Fail2ban or CrowdSec containers are running. The check is performed by inspecting the 'image' column.

# Check docker container running fail2ban
if docker ps -a | awk '{print $2}' | grep "fail2ban"; then
    IPS_INSTALLED=1
    docker ps | grep -q "fail2ban" && IPS_ACTIVE=1
fi

# Check docker container running crowdsec
if docker ps -a | awk '{print $2}' | grep "crowdsec"; then
    IPS_INSTALLED=1
    docker ps | grep -q "crowdsec" && IPS_ACTIVE=1
fi

thanks for catching that @alvarosaavedrau but, the changes don’t gracefully handle cases where docker is not available on the system.

Completely agree, if docker is not installed it will fail. I have made a new commit to verify that docker is installed and running.
