Reconsider gc implementation
As pointed out in discussion in #1691, we should reconsider `gc` implementation.
Currently, if called without any options, dvc will collect current branch dependencies and outputs checksums, and remove everything besides it. We can easily clear history of changes with this command. `gc` should be safer with default options. Straightforward implementation could get all outputs for all revisions in git repo and remove everything that is not on list.

As pointed out by @Suor, this approach might be slow for repository with long history.
