Feat/ PreSync mode #270

Commits on Oct 18, 2024

  1. feat(pre-sync-mode): add an optional pre-copy stage to reduce downtime 

    permits to reduce the downtime for the actual migration: we create the
destination PVCs and already rsync the data, without having to scale
down the pods/deployments/statefulsets.
once the copy/rsync stage is complete, we pursue by scaling down pods,
doing another copy/rsync (to ensure data consistency), finally swapping
the PVCs and scaling up

fix: proper matching PVCs count
feat:  add max-pvs=n flags
feat(pre-sync-mode): run a "prefetch" copy before actually migrating
