As part of legacy/trac#32740, we need to sync OONI's test results with BridgeDB's SQLite database; in particular its BlockedBridges table. [Over here](https://trac.torproject.org/projects/tor/ticket/32126#comment:4) and [here](https://github.com/ooni/backend/issues/396#issuecomment-620611456), hellais suggested to set up a copy of OONI's MetaDB and have it sync with their canonical database. We can then use our local copy on polyanthum to update BridgeDB's SQLite database. Instructions for setting up a MetaDB are available at: https://github.com/ooni/sysadmin/blob/master/docs/metadb-sharing.md
