remap prefix to Control + a

Simplecov aggregated coverage report from CircleCI 2.0 parallel builds (focused on storing locally/within CI containers as artifacts)

Problem Statement

We have Rails application which is running tests on circleCI 2.0, we have simplecov configured to track the coverage of our test suite. Now the problem is with parallelism enabled, we have partial coverage reports in all different containers according to the tests those containers ran.

We obviously want to have consolidated simplecov coverage report which actually shows us overall coverage report.
