Execute bundle from a pre-computed Run

[kichristensen]

What does this change

This takes Carolyns draft PR #2722, and "merges" it with the main branch, but it also removes some parts from the PR that unrelated to the actual functionality.

From Carolyns draft PR:

Update our CNAB runtime implementation to accept a pre-computed Run, which may have already been persisted in a pending state. We now execute it as defined and have moved more of the logic for how the bundle should be executed out of the runtime. This allows us to generate the runs ahead of time, store them on a workflow, and execute later.

What issue does it fix

Closes #2732

Notes for the reviewer

From Carolyns draft PR:

I have carved out in the runtime where we should do JIT resolution of parameters and credentials. Credentials have always been resolved JIT, but parameters are still being resolved earlier. The rest of the fix will come in a follow-up PR for #2698

I am moving away from using intermediate representations of resolved credentials and parameters in favor of using the existing field on parameter/credential sets that store the resolved value. In a follow-up PR (this was too big to include), I complete the switch over so that we delay resolution as much as possible and avoid excessive type conversions from string to the typed value (e.g. "3" -> 3).

If this PR is accepted a follow up story, as described above, should be created probably be created to remember it.

This is a future nit: run.Parameters.Parameters should have a different naming scheme, run.ParametersSets.Parameters or something more to what it really is.

I've been kicking this one for awhile to make sure it is "safe".
It looks good.
