skip redirector policy udpate in update_redirector_policy if proxy sever has not started yet.

[Zhidong Peng (ZhidongPeng)]

Context: GPA service redirects the azure host endpoints connections to localhost:3080, if the proxy_server could not bind to this local port. the redirected connections may reach random http://localhost:3080
Fix: check proxy server provisioning state, if it has not provisioned yet, skip update the redirector update policy. The redirector update will be happened only when Provision ALL_READY.
