another attempt to fix concurrent metric collector test

[dgghinea]

Maybe 70000 goroutines in a single test was a bit too much

By removing this we are reducing the number of concurrent metrics being given to the SDK, I think by removing this we are invalidating the purpose of the test.

can not see the benefit of reducing this invalidating the reason for the test

[dgghinea]

@jcollins-axway it's not exactly removing the test, it's reducing its usage. I think the test is still valid but it's testing 2800 concurrent calls instead of 70000.
I initially thought this was the reason the GitLab runner was failing. but if you think this is not related, I can just close this.

@dgghinea is it helping anything with the reduction?

I took a look and the time of the test pipeline to finish went from around ~9 mins to 3.5 mins(specifically, the test that was modified went from ~300s to 4s). So I'd say yes
