Thomas Orozco 6c29aad4a0 mononoke/blobstore_healer: handle missing regions gracefully ... Summary: There's a few things broken with common/rust/sql and the blobstore healer's handling of replication lag right now: - If Seconds_Behind_Master isn't an int (it'll be NULL if replications is paused), it just panics. - If it's talking to a server that it expected to be a replica but is a master, it returns None for the replication lag, but 0 would be more appropriate. - If a region no longer has a replica, it errors out. This diff fixes that: - If replication is paused, we return None for lag. - If we're talking to a master, we return 0. - If a region has no replica, we ignore it.
