--full-run mode

[alexsavulescu]

For time-wise constraints (i.e. CI) we tamper with tstop across various models. It is worth implementing --full-run mode that will allow us to perform further validations of existing models.

Foreseeable impact:

• add a new entry in MODELDB_RUN_FILE for tstop
• isolate tstop tampering from the script entry

Considerations:

• would it be possible to have a CI that takes lots of hours for all models? or is it smtg we need to perform manully?
• can we make use of diffgout in the CI for better understanding of differences? (this may be worth an issue on its own)
