MXS-2273 Introduce SERVER_BEING_DRAINED bit
...
With this bit set, existing connections to a server should not be
closed, but no new connections should be created to the server.
The bits have also slight been rearranged.
- Bits 0 - 15 are now reserved for bits applicable to all servers
- Bits 16 - 31 are monitor specific
Further, the cases whether a server can be connected to and whether
it can be used, but be separated.

MXS-2223 Log a message when a slave is discriminated due to replication lag
...
Both the replication lag and the message printing state are saved in SERVER,
although the values are mostly used by readwritesplit. A log message is printed
both when a server goes over the limit and when it comes back below.
Because of concurrency issues, a message may be printed multiple times before
different threads detect the new message state.
Documentation updated to explain the change.
