Hey,

I've noticed that on 1.3.0-beta.1 when petset is deleted its pods stay alive:

core@master ~ $ kubectl get petsets | grep mariadb
mariadb-galera 3 3 7s
core@master ~ $ kubectl get pods | grep mariadb-galera
mariadb-galera-0 1/1 Running 0 5s
mariadb-galera-1 1/1 Running 0 4s
mariadb-galera-2 1/1 Running 0 3s
core@master ~ $ kubectl delete petset mariadb-galera
petset "mariadb-galera" deleted
core@master ~ $ kubectl get pods | grep mariadb-galera
mariadb-galera-0 1/1 Running 0 18s
mariadb-galera-1 1/1 Running 0 17s
mariadb-galera-2 1/1 Running 0 16s
core@master ~ $ kubectl get petsets | grep mariadb-galera
core@master ~ $

Cheers
