Cron job for entities with status pending

[maestre3d]

Is your feature request related to a problem? Please describe.
Whenever a new entity is created, in most of the cases it will start a transaction.
The problem here is sometimes there will be leftovers if some problem occurred.

Describe the solution you'd like
It would be better if we implemented a cron job inside every service in a goroutine/thread that will run every X time (from min to days), where we could remove (hard-remove) every entity with the "STATUS_PENDING" state.

Describe alternatives you've considered
Any.
