preferences only if the driver is connected to a replica set, otherwise the read preferences are ignored.
This function uses the driver's current knowledge of the state of the MongoDB server or servers it is
connected to; it does no I/O and it does not block.
PARAMETERS
• td: A mongoc_topology_description_t.
• read_prefs: A mongoc_read_prefs_t or NULL for default read preferences.
RETURNS
True if there is a known server matching prefs.
