MXS-3836: Document refresh_databases "behavior"

Browse Source 
The fact that the parameter does nothing in 2.4 and newer versions is now
at least documented. Fixing it this late in 2.4 could result in unwanted
changes in behavior.

### `refresh_databases`
**Note:** This parameter does nothing in 2.4 and newer versions. The
database map is only created when the session starts. Follow
[MXS-3836](https://jira.mariadb.org/browse/MXS-3836) for more
information.
Enable database map refreshing mid-session. These are triggered by a failure to
change the database i.e. `USE ...` queries.
