Review Comment:
Not sure about the `RESTORE` - we need to use the same names as we use other
filters.
```
"Enable transaction event filtering to save dump space.\n" +
"When true, OPEN TXN events do not get dumped on the source server, "
+
"and transactions on the target server are implicitly opened during
REPL RESTORE.\n" +
"The default setting is false");
```
We want this config to be around the other `REPL` related configs, not at
the end of the list.

> REPL DUMP is replication all OpenXacts, even when they are from other non
> replicated databases. This wastes space in the dump, and ends up opening
> unneeded transactions during REPL LOAD.
>
> Add a config property for replication that filters out OpenXact events during
> REPL DUMP. During REPL LOAD, the txns can be implicitly opened when the
> ALLOC_WRITE_ID is processed. For CommitTxn and AbortTxn, dump only if WRITE
> ID was allocated.
