Fix check if restore in progress

When performing the BnR procedure with the wipe_ceph_osds
flag and the rook-ceph backend configured, an error was
given when removing the app.

This happened because a restore in progress check in the
DB was done in the app's lifecycle and false was always
returned, as the insert had not yet been performed before
this task.

To fix this, the database query has been replaced by
checking the '/etc/platform/.restore_in_progress' flag.

Test Plan:
- PASS: Build rook-ceph app
- PASS: optimized AIO-SX B&R with wipe_ceph_osds flag
- PASS: legacy STD + DX B&R with wipe_ceph_osds flag
