Create Security Zone and Security Policy for GRE Tunnels Creation

GRE tunnels created by the Zscaler Cloudblade must require a security policy (v1) or security policy set(v2) to be applied to the site for tunnel creation. The security policy and zone must be created and mapped to the site. The Cloudblade automatically places the servicelink GRE tunnel into the security zone. The CloudBlade typically creates two GRE tunnels, a Primary tunnel to Data center one and a Secondary GRE tunnel to Data center two.
If a policy or zone is removed later, the CloudBlade ignores all GRE operations performed on that site. This includes creating, updating or re-querying.
