@lbajsarowicz could you please clarify why Inventory cron jobs should be in a separate group?

[lbajsarowicz]

1. It's very common that there are multiple Jobs added to <group id="default">, some of them cause failures or locks, and then some of the tasks are not being run. DevOps / SysOps experts run different Cron Groups separately to avoid such situations: cron:run --group=index isolated from cron:run --group=default etc. To sum up: It's more reliable to have a separate group for all Inventory-related tasks.
2. While running Functional Tests, I'd love to have the possibility of running only the tasks related to Inventory management, not all the cron jobs. I need to make sure that the Functional Test result is not a coincidence of other processes taking part in the default cron group. So it is more testable to have them isolated.
