Create periodic jobs for scenarios

These jobs will be used for promoting scenarios based on deployment
and testing on baremetal.

The jobs are currently triggered daily without checking if anything
changed. This will be updated and they will only be triggered if
infra/engine or infra/swconfig/<scenario> change so we build only
when something happens.

Promotion logic is not implemented yet and will be done in a separate
change.

In addition to periodic jobs for scenarios, trigger for baremetal
engine periodic job is switched to daily in order to free up time
for scenario periodic jobs.

And as usual, lots of duplications here and there and these will be
fixed by refactoring jobs and scripts once the basic pipeline is
in place.
