[fix][broker]: validation for at least one TlsUrl / nonTlsUrl is present for cluster creation/update

[niharrathod]

Fixes #19866

Motivation

Verify either TlsUrl or nonTlsUrl is provided as part of Cluster create and update operation.
This validation is not applicable for "global" cluster create / update operation.

• Added validation either serviceUrl or serviceUrlTls is set as part of cluster creation and update API.
• Added validation either brokerServiceUrl or brokerServiceUrlTls is set as part of cluster creation and update API.
• Added unit test cases.
• Fixed old test-cases.

Core changes are only in two files ClustersBase.java, ClusterDataImpl.java, added unit test w.r.t same in ClusterDataTest.java
rest 115 file diff is because of patching existing test cases.

At first site this looks big change, but actual changes are only in two files ClustersBase.java, ClusterDataImpl.java where validation is added, unit test w.r.t same in ClusterDataTest.java, rest 115 file diff is because of patching existing test cases, where brokerServiceUrl is set to satisfy the validation.

Kindly requesting for a review. I am happy to discuss & do any improvisation / further work if needed.
