Add argument to run for submitting targets without IO checks

[dansondergaard]

I think that we could do something like this:

1. Add a --force flag to gwf run. When the flag is given, gwf will not do any checks to see if a target should be submitted, but just submit it and their dependencies.
2. Add a --no-deps flag to gwf run. When the flag is given, gwf run will only submit the targets matching the given pattern, but not their dependencies.

So running gwf run --force --no-deps *my_target* will submit the matching targets, without their dependencies, and without probing the filesystem for changes.

That sounds great!

I guess --force would run all dependencies then. Would it make sense to allow setting a number of "dependency levels" to compute? So where --no-deps would be 0, you could allow running N steps down the three?

[dansondergaard]

It's possible, but sounds like a very niche feature :) You could sounds the (almost) same problem by giving the dependencies to gwf run directly, like gwf run --force '*layer1*' '*layer2*', etc., which is already possible.

[LudvigOlsen]

True! gwf run --force --no-deps would work for my situation for sure. And force would allow rerunning everything without removing files (could be a mess if it fails midway though).

Great! I have commented on #416 separately.
