Hi @Rachit-Chaudhary11, looks like the previous PR #56 cloud cover this.

Hi @haorenfsa I see that the above PR is created for QueryNode, DataNode, IndexNode and Proxy. While this PR is for the different Milvus Coordinators.
Even after merging the above PR the coordinators will still not have the rolling update, which will be handled by this PR

Hi !
Don't you think you should use the same syntax as PR #56 to add strategy using "with"/"toYaml" ? This will allow users to completely have the freedom to customize this part according to their need.

Another point, using .Values.DeploymentUpdate means you force users to use the same strategy for all coords. Since nobody provide great best practices for either coords or nodes, I think we should let users customize each coords at this moment (this is just my opinion ;) )
