* experiments: add initial local tmpdir executor
* fix detached head pull
* experiments: include unchanged (unrepro'd) stages in experiment hash
* experiments: repro single experiment using tmpdir executor by default
* stage experiments as stash commits before running
* include repro args/kwargs in stashed experiments
* support running arbitrary experiment commits (including stash commits)
* experiments: use ProcessPoolExecutor
* experiments: add `dvc exp` alias for `dvc experiments`
* experiments: add `dvc repro --experiment --queue`
* `--queue` can be used to stage an experiment for future execution
* experiments: show queued (unexecuted) experiments in `dvc exp show`
* revert ProcessPoolExecutor change
* experiments: add `dvc repro --run-all [--jobs]`
* `--run-all` can be used to run all queued experiments in parallel
* cleanup output
* experiments: use ProcessPoolExecutor
* fix returning unpicklable objects error
* update tests
* fix windows cleanup issue
* on windows tempdir cannot be removed if we are chdir'd into that
directory
* experiments: add initial experiments.show
* only includes metrics + params (no code/data information)
* experiments: basic `dvc experiments show` functionality
* experiments: clone and run repro inside clone workspace
* repro: add -e/--experiment option
* experiments: hash experiments to identify duplicates
* experiments: update show
* experiments: checkout experiment after running repro
* experiments: add `dvc experiments checkout`
* experiments: add simple `dvc experiments diff` command
* just shows combined output from `metrics diff` and `plots diff` for
now
* add very simple tests
* add some useful output messages
* experiments: suppress help messages while feature is in development
* experiment related commands will be accessible but hidden from the
default command help messages
* add simple experiments command tests
* experiments: disable feature by default
* experiments only enabled in test environment (DVC_TEST) or when
core.experiments config option is true
* use fetch on checkout missing revs
