fetch: review sample command output

[jorgeorpinel]

For example from static/docs/commands-reference/fetch.md line 204+:

$ dvc checkout
Checking out '{'scheme': 'local', 'path': '.../example-get-started/model.pkl'}' with cache '3863d0e317dee0a55c4e59d2ec0eef33'.
...

Extracted from #549 (review)

The effort for this may be too great. Perhaps we should rather think of a way that will be sustainable in the future to make sure all our code and console examples remain valid as DVC changes. For example generating them all from scripts in a separate docs-code-examples-dev Git repo, similar to https://github.com/iterative/example-repos-dev ?

I would just create a small tickets from time to time to update it. I don't think we need a special machinery around this. At least now. Too much effort.

As part of this one, I would just grep "{scheme ...}" messages and replace them with human readable versions. It should be straightforward and should not require running all these examples, I hope.

$ dvc checkout
Checking out '{'scheme': ...

was just an example. I meant absolutely all the ```dvc code block examples, basically. There's 450 :/

[shcheklein]

Yep, I +1 on that it's too much of a scope to update them. But also I'm not sure we need some very specific mechanism to keep them up-to-date. At least for now. Let's just do the best we can when we update docs.

[jorgeorpinel]

Fair enough! Hopefully we can count on users reporting any problems via issues.

[shcheklein]

I meant - let's open this particular one open :) Just fix fetch examples. And may be similar outputs around.
