Deadlocks while trying to write dumps and uploading them to database at the same time

[gauzy-gossamer]

There are two locks (FileDumper.mu and Clickhouse.mu) that are called in different order.

When dumping files to disk Clickhouse.Dump locks Clickhouse.mu, then FileDumper.Dump is called with a lock on FileDumper.mu. At the same time, FileDumper.Listen calls ProcessNextDump with a FileDumper.mu lock and then calls SendQuery->GetNextQuery with a Clickhouse.mu lock.

One potential solution is to remove a lock from Clickhouse.Dump, since it already locks FileDumper.mu in FileDumper.Dump.
