Remove scanAll which relies on the "shareinfo" endpoint that returns the full cache tree. The latter can become big for big shares and result in timeouts. Furthermode, the full tree would be retrieved again for each and every detected change which can become expensive quickly. Signed-off-by: Vincent Petry <vincent@nextcloud.com>
