Issue:
Show default in `dvc remote list`
`dvc remote list` does not show which is the default. It would be very helpful to add this as another column.

Discussion:
RMCrean: Thanks for the suggestions and advice, I've added a new commit to implement idea 2 which I think is now ready for review. I decide to not change the ordering or the remotes (to put the default first) like I had initially done for the sake of keeping the code simpler. Of course, happy to reorder if preferred.

Regarding the failed test, my understanding is this is not related to this PR?
