Consistent argument name for a model output tbl

[elray1]

We have 4 different packages with 4 different names for this argument:

• hubData::coerce_to_hub_schema: uses tbl
• hubVis::plot_step_ahead_model_output: uses model_output_data
• hubEnsembles::simple_ensemble: uses model_outputs
• hubEvals::transform_point_model_out: in progress, not yet committed, uses model_out_tbl.

Let's pick one name for this argument and use it in all of our packages

Just a note that the hubData argument does not belong on this list because it refers to submission data rather than data that has been successfuly assimilated into a hub. For example, it never contains a model_id column which model_out_dfs always do.

It was decided in dev meeting to standardized argument name for model output tbls to model_out_tbl. I will open issue in the 3 packages concern by that.
