dvc repro foreach stage name should auto-expand all stages

[schuhschuh]

Similar to #6035 but without the aspect of running the stages in parallel (which would be great but a separate issue), it would be great if one can run dvc repro foreach_stage_name which then get expanded to all the individual stages which DVC produces from the foreach stage. It can be annoying and cumbersome having to specify each foreach_stage_name@substage_name_or_id separately.

Given dvc.yaml:

stages:
  foreach_stage_name:
    foreach:
      - a
      - b
    do:
      ...

it should be possible to run dvc repro foreach_stage_name. Currently, I have to run

dvc repro foreach_stage_name@a foreach_stage_name@b

Looking at the documentation of dvc repro, it appears this could be done using --glob:

dvc repro --glob "foreach_stage_name@*"

While this satisfies my use case, I still wonder if for foreach stages it would make sense to not have to use an explicit glob pattern? Given the special @ separator in the stage names and the stage key specified when editing the dvc.yaml. Intuitively, I thought this should work. When it didn't, I hadn't realized that the --glob option existed until now.

@schuhschuh, this is already supported. DVC will run all of the expanded stages with just the foreach_stage_name.

Oh, nice. I admit I haven't tried this since with newer versions. Thanks!

@schuhschuh, this was introduced together with the same feature in 2.0. It might have been the case that the other stage did not need to be reproduced.
