Real time coverage info in VS Code

[smadala]

Description

• This idea inspired by Scott Hanselman blog(@shanselman) and .NET Core developers( special thanks to @sesispla for bring blog to our attention) ask from vstest issue

• As user write new/update test and save the test file, the coverage info should update for product/test file in VS Code.

Steps to reproduce

• dotnet new mstest
• dotnet add package spekt.vstest.coverage.report --version 0.0.1-beta-01 --source https://www.myget.org/F/spekt/api/v3/index.json
• dotnet watch test --collect "Code coverage"

Expected behavior

• Something similar to

Actual behavior

• Currently user need VS Enterprise to view code coverage results from .coverage file (Eg coverage file: C:\Users\samadala\tmp\cc-mstest\TestResults\ab987d22-bcc9-4748-a04d-071bbe9851c3\samadala_SAMADALA_2018-07-23.18_54_39.coverage)

So we need a new vscode extension to watch for .lcov file and update the editor with coverage info?
