User should be able to add global variables at application level which can be utilized in tests and flows.
Currently, I see we can set them at environment level. We would have more than 50 global parameters in our test suite which are common across all environments (QA, STG, Dev, single clusters, etc.). It would be too much effort to set them up for each environment where they are going to be same value. Again, if we have to change some values which we do periodically, we will have to do for all environments which also seems too much effort to maintain the test suite.
