[dev] Separate ssh IP and ws-proxy IP

[iQQBot]

Description

In #9786 we introduce a special domain for ssh gateway
This PR change harvester base preview environment use this special domain
This has some benefit

1. Save some money, before, accessing workspace pages also required the use of loadbalancer, which consumed some unnecessary traffic, after this PR, all non-SSH traffic will no longer go through loadbalancer
2. To improve some stability, kubectl port-forward is not very stable, for example, vm sometimes need to rebuild, then kubectl will time out, and the pod will restart, this restart time will have exponential growth, we do not want to bring this instability to the users who do not use SSH Gateway
