Fix Nginx lb in k8s/istio
- Provide workaround to make nginx lb work properly - nginx_client sample can modify default load balancing from three to two servers at runtime - Ensure port 9180 is used for default deploy for lb and servers - Modify render_yaml to specify deploy_name so that clover-server1, 2, 3 can be used for default lb config - Ensure proxy template is aligned to lb to allow the source IP from originating host to be propagated to final destination - Fix default nginx proxy server_name to 'proxy-access-control' and change default proxy destination to 'http-lb' - Split lb service_type to 'lbv1' and 'lbv2' to provide an example of how to modify the run-time configuration of the load balancer after deployment - modify http-lb-v2 to use clover-server4/5 instead of the defualt clover-server1/2/3 - modify http-lb-v1 to use clover-server1/2 instead of 1/2/3 - Aligned pod IP retrival method with nginx_client.py Change-Id: I73fa60a69c93ae1e82a477ef6283c00f67a21360 Signed-off-by: Eddie Arrage <eddie.arrage@huawei.com> (cherry picked from commit 5e213108dfade163a85cff9b9156de9bd2c18887)
