[Chore] Fix code climate reports

[danail-branekov]

Background

The links to the Codeclimate reports on the README are broken!

It seems the the reporting aspect of codeclimate has forked into a new company - qlty.sh (details here)

There is a migration guide that describes what one needs to do. Note that the migration guide starts with the following disclaimer:

Any attempts to upload coverage to the Code Climate API (via the cc-test-reporter) will result in failed CI builds.

To avoid disruption, you must remove (or comment out) any remaining references to the old cc-test-reporter within your CI scripts.

That disclaimer explains why our ci image build fails (the cc-test-reporter seems to be no longer supported)

Action to take

Consider what we want to do with those reports:

Option A: Get rid of them. I personally do not find them much useful. OTOH, we could brag with code coverage and code maintanability

Option B: Execute the migration guide

Impact

Green CI, maybe fixed quality reports

Dev Notes

No response

After a discussion with @georgethebeatle we agreed that besides migration to qlty being a significant amount of work, qlty cli does not seem to support the gocov coverage reports (something that cc-test-reporter did).

That is why we decided to disable the coverage reports on both CI and README

@danail-branekov This issue can be closed since you picked 'Option A' and made the necessary changes?
