* stage: make runs checkpointable
* api: add make_checkpoint API call
* tests: add test for checkpointed stage
* experiments: implement checkpoints callback chain
* initial working state
* use .dvc/tmp for checkpoint signal file location
* force repro for checkpoint experiments
* checkout: add flag to allow missing persistent outputs
(i.e. not yet created)
* use allow_persist_missing on checkpoint experiment repro
* executor: force checkout before checkpoints experiment repro
* move checkpoint commands to `dvc exp run`
* support resuming checkpoint runs with --continue
* fix git bugs
* experiments: include checkpoint commits in `exp show`
* use 1sec sleep timers
* fix apply_workspace test conflict
* tests: add test for `dvc exp run`
* cleanup signal file behavior
* fix bool conversion
* tests: add tests for checkpoint and checkpoint_continue
* fix styling
* fix checkpoint stage test
* fix checkpoint monitor thread condition/notification
* plots: add -e/--experiment option for plots diff
* experiments: add method to get baseline for a given experiment
* plots: default to diff against baseline instead of workspace/head for experiments
* use exact match for experiments RE since name-rev may return relative
commits
* executor: abstract tmpdir population using tree upload
* experiments: unmark flaky test
* fix wrong tree download
* LocalTree: use os.replace instead of os.rename in _upload
* 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
