Allow searching for members

[jelaplan]

Problem
Users can't search for members of a dataset. They can only search or data sets themselves.

Solution
Allow searching for the names of members as a more detailed thing to access.

It is very important for out organisation, that some kind of search possibility or filter is provided, as our source code is placed in one (!) dataset per environment. Imagine scrolling a member list in Zowe/VS Code with more than 200K members...

You can filter the document trees in Visual Studio Code -> https://code.visualstudio.com/docs/getstarted/userinterface#_filtering-the-document-tree

Below is a quick GIF to see it in action. I'd be interested to see if it works with so many members.

you can use Ctrl + ALT + P to filter the members that you are looking for. This was implemented by PR #592

@MikeBauerCA Yes it works. This was tested before and results can be found in issue #327

[MikeBauerCA]

@jellypuno after opening the PDS to see the 30k members, did you try to perform the local filter? Was it immediate?

[jellypuno]

@MikeBauerCA We have an issue with the filtering 😆 . I opened issue #992 .

[MikeBauerCA]

You can still filter the trees using the method I described above though. Not sure if you still have that large PDS to try it out on.

Have used the "filter the document trees in Visual Studio Code" for the first time... Wonder why I havent seen this before !?
It seems like it filters within the VS Code "frontend", hence our problem is not solved as we have 200K+ in one single production source library... usually this is not an issue...

In regards to Ctrl + ALT + P, a few of us in the office have tried it, and we all get "Enter pattern..."
Where do we learn what "pattern" should look like, since nothing happens, no matter what we type in ?

It appears we need to enhance the Zowe Node SDK to support the start and pattern query parameters of the REST endpoint (https://www.ibm.com/support/knowledgecenter/SSLTBW_2.4.0/com.ibm.zos.v2r4.izua700/IZUHPINFO_API_GetListDataSetMembers.htm) and then leverage this in both Zowe Explorer and Zowe CLI.

Out of curiosity... what about setting the X-IBM-Max-Items ? It appears that we do not receive the total number of members in the dataset.
