Story: Compare other branches and commits in plots and the experiments table

[dberenbaum]

In the Plots and Experiments views, is it possible to compare the workspace or experiments to past commits or branches? Right now, it seems limited to experiments based on the current commit. For example, in plots it would be nice to be able to enter any git ref here:

Im preparing also an issue regarding to branches 😋

Close to a duplicate of #456. I think we only need one of these issues.

I don't think we should be constrained by existing CLI flags here like --all-branches etc. VS Code might be able to provide way more flexibility to pick and choose specific refs from the git tree within the UI. I think this type of functionality could be broadly useful not just in this feature, but in other features like removing unwanted experiments or data.

#2392 Displays the previous two commits. Next step could be have a "show more commits" at the bottom of the table. It could add two (we can easily fine tune that to the number we want) more commits until there are no more to show.
