perf: test-suit loader improvement - [INS-4400]

[CurryYangxx]

Issue
When the nesting levels are deeper or there are too much children under workspace. The withDescendants will take a long time to find all requests.

Changes

• Add a queryType param for withDescendants function to limit the types of database queries
• pass stopType and queryType when call the withDescendants function in test-suit loader

An alternative implementation would look like replacing stopType with queryType as they have overlapping behaviour.

Note: there are only 3 usages of stopType in the code and they all stop on request type, you could just set request as the query type and remove that argument completely.

@jackkav The request may not be a direct child of workspace, but a child of requestGroup. So we need to include both request and requestGroup in queryType, and let the query stop at reques type.
