DNS resolution change for Google Compute Engine

In the coming months, all VMs in newly created Compute Engine projects will use zonal DNS names by default. These VMs' DNS configuration will differ from current VMs in the following ways:

• The "search" entry in resolv.conf ("c.[PROJECT_ID].internal") will be changed to "[ZONE].c.[PROJECT_ID].internal"
• The VM domain name ("c.[project-id].internal") will be changed to "[zone].c.[project-id].internal"
• The VM fully-qualified domain name ("[vm-name].c.[project-id].internal") will change to "[vm-name].[zone].c.[project-id].internal"
