osd: adjust osd_delete_sleep_ssd[_hybrid]

1) Do not differentiate all-flash and hybrid(ssd+hdd) deployments since
they both bound to SSD drive backing DB volume.
2) Drop osd_delete_sleep_hybrid from 2s to 1s
3) Raise osd_delete_sleep_ssd to 1s since 0 is a way too low - having
it that low tend to cause a significant negative imact on OSD's regular
operation.
