Show which sources changed when running a task with verbose

[abrahammurciano]

Just like when you have a task with status checks, and you run it with -vv, it will log that it ran the command and show the status code, it would be useful if it also shows which sources were updated and which were not.

For example it would help me debug why a dependency of a task is running again after it was just run explicitly and all the status checks exited zero. I'd like to know which entry listed in sources it claims was changed so I can check if it was indeed changed and why
