This change will add logic to the put rollup api that fails if no rollup job is active and no rollup index exists in the cluster. The logic first check whether there is an active rollup persistent task if there are no active rollup persistent tasks, then it checks whether any rollup index exists. The latter check is an expensive check, but assuming that it only runs as part of the pu rollup job api and only when there are no rollup jobs, this should be ok. All tests that invoke the pu rollup job api will need to be adjusted to create a dummy index that has rollup mapping metadata. Otherwise, tests can't create a rollup job. Closes elastic#108381

Do we want to do something in the Kibana management UI to prevent users from creating new rollup jobs? |

@rayafratkina Apologies for the late reply. Maybe my memory isn't correct, but I thought we already highlight that rollup is deprecated? I think the UI should highlight that rollup is deprecated (if we haven't done already) and will be removed. Additionally I think it makes sense to warn users that creating a rollup job in an cluster with no rollup usage will fail. |

The rollup feature was never GA-ed and is still tech preview. It has been deprecated since 8.11.0 in favor of downsampling. At some point the rollup functionality will be removed. In order to prepare for the removal of rollup, the creation of rollup in clusters with no rollup usage will be prohibited. To avoid any new usages of rollup while it is scheduled to be removed.
