Opt ServiceEntry validate message

[j2gg0s]

Please provide a description of this PR:

"If we enable DNS auto allocation and cache, addresses are not required for the ServiceEntry of the TCP. Although we cannot determine whether the relevant configuration is enabled during the validation, including this information in the warn message is still very helpful to users."

Hi @j2gg0s. Thanks for your PR.

I'm waiting for a istio member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

@j2gg0s thanks for the PR! Looks like there is some conflict resolution needed though
