Filter individual testcases by tags

[swrdfish]

Description

The current implementation of tags allows users to filter test files based on tags. An user on discord @skelkar wanted to filter testcases by tags.

Usecase: Suppose 5 .js files, each has 10 tests within 5 describe blocks (one describe block - 10 it bock in one .js file). Testcases are clubbed together with related functionality in mind.
Supposer 5 cases are identified, one from each .js file, as sanity. A user should be able to run these 5 only.
