Update provision test stage of PR pipeline, so that it can collect logs/restore monitoring stack after cluster-reuse check

[dimakr]

A check has been added for reuse cluster functionality of SCT, in scope of https://github.com/scylladb/qa-tasks/issues/1749.

Logs collection/restoring monitoring stack is performed only for initial run of provision test, but not for rerun when reusing the cluster, as collecting after reuse might be problematic since everything would be duplicated.
We need to update the provision stage pipeline to handle this case of collecting multiple logs sets when reuse cluster is checked.

If there will be a requirement, we will fix it.
