Vscode-extension-for-zowe: Copy and Rename is taking a long time to re-load

[jellypuno]

This is related to issue #327

I have a dataset with 30k members. I am able to load and edit it normally but when I tried to copy and rename a member, the re-load for the tree is taking a long time. It took at least 5 mins before this error message appears:

@jellypuno With rename the reason is we do parent node refresh, instead of just element refresh. So I guess it should be reworked.
renameDataSet(of extension.ts) method is the target for such changes.
Also what should be refactored - the fact we do such changes even if rename request has failed, you can see it in the same method.

@jellypuno I checked how rename works for the dataset, in the case if it fails further rename operation will be prevented, so only refresh should be refactored.

Is the issue only when renaming members? If so that is handled by renameDataSetMember. The parent node is refreshed here too but it looks like that isn't needed

@CForrest97 In issue #327 , there is a BOX link (in the end) of the research that I have concerning this.

@jellypuno Ive created a branch which should fix renaming members for large data sets, once Ive done some more testing I can create a PR for this and take a look at copying too https://github.com/zowe/vscode-extension-for-zowe/tree/470-rename-members-fix-for-large-sets
