Add SQL create data/schema region

[Yongzao Dan]

Hi,
  I'm planning to add a SQL for IoTDB cluster version. Here are the 
details of this SQL:


  Motivation: We don't have enough evidence to design an 
optimal RegionGroup expansion algorithm yet. 
If a large number of devices are created in a StorageGroup and the 
SeriesPartitionSlot is filled, the current algorithm cannot 
expand RegionGroup anymore. 
Therefore, we need a special SQL to enable DBA 
expand RegionGroup manually.


  Syntax Definition: create (data | schema) region on prefixPath(Represent 
a specific StorageGroup)


  Function Definition: Create a new data/schema RegionGroup for the 
specific StorageGroup.

I think choices 2 might be better, because this helps distinguish ConfigNode 
from DataNode Best,

Hi,

I want to change a pair of misleading parameter names.

iotdb-datanode.properties: config_nodes -> target_config_nodes
iotdb-confignode.properties: config_nodes -> target_config_nodes

This pair of parameters represent only one or more target ConfigNodes that can 
communicate with when a new Node needs to join the cluster during startup.
Furthermore, the modification of ConfigNode list caused by the cluster capacity 
expasion or diminution are controlled by internal logic, we don't need to 
change these parameters every time.

Please take a look.
