node types. Add getCellListForID() in which is computed the cell related to an
OID or TID. Add _getPartitionTable() accessor in client application that check
if the master connection is established or not, and reconnect to obtain the last
partition table. Move the connecting_to_master_node lock in the accessors
instead of connectToPrimaryMaster(). This latter method is also set as private.
Note that the connection to primary master is not established at client startup
but when trying to access to the partition table or the primary connection. 
Split tests for the partition table and update others tests altered with changes
above. Fix a database name for mysqldb module, remove some unused import.
