Ruben Hensen 175769d36c Add a tool to VACUUM the k8s-dqlite database ...

dqlite supports VACUUM from v1.18.2, which microk8s 1.34 ships, but the dqlite shell wraps every statement in a transaction and SQLite refuses to VACUUM inside one. dqlite-vacuum sends it through the go-dqlite driver instead and otherwise just prints page statistics. dqlite-vacuum.sh makes the backups first.

Rehearsed on opti1 on a throwaway node in /dev/shm: 657 MB to 41 MB in 0.6s, with concurrent writes unaffected and the data intact after restarts.
