Add option to start executing task from step X

[kosovojs]

Description

Would be nice to be able to start execution of task from any step (something like task do_stuff --from-step 4).

Some of my taskfiles are just running some ETL-like processes and i don't have any good way of using existing functionality to skip steps (or... not wanting to hack my way into (ab)using those). Sometimes task fails at initial steps. Then i usually have to copy task definition and create a new task with only required steps, or i have to comment out the steps i don't want to run, which i can forget about :) So something like proposed "--from-step 4" would really help.

Sure, this can be expanded into "--skip-steps 2,3,6,8" and "--run-steps 3,8,9,15", but i would think that "--from-step" would be a good start. If any of steps are other tasks, i would consider them as "one step", not the amount of steps that sub-task (and possibly subtasks of that subtask) would have. Probably the same goes with loops - that would be considered "one step", where it makes sense.

Hi @kosovojs,

To me this looks like something that would be complicated to maintain and potentially error-prone.

Also, no one has asked for that in all these years, so this is not a largely wanted feature.

I'm closing for now, but anyone is free to still comment if you think this would be useful.

@kosovojs you can achieve this by restructuring your tasks and using 'status' and/or ''precondition'. If you open a discussion topic some will surely help you.
