Firewall rule per machine

**Is your feature request related to a problem? Please describe.**
Right now we have firewall rules in the terraform scripts which we deploy in the GCP and some of them are overcomplicated and maybe not really needed. Since we introduced Packer we can have some or maybe all of them in host-based and reduce the really big list of terraform firewall rules.

**Describe the solution you'd like**
Check what firewall rules we have in the terraform scripts and apply those in each packer script that we have.

**Describe alternatives you've considered**
Leave it as it is and lets leave in small chaos 😄
