cmapi should do more consistency checks

Cmapi should do more consitency check to avoid weird situations.

1.
Check inconsistencies in columnstore.xml over all nodes,

For example:

Node1:
<ModuleDBRootID1-1-3>1</ModuleDBRootID1-1-3>
<ModuleDBRootID1-2-3>2</ModuleDBRootID1-2-3>
<ModuleDBRootID1-3-3>3</ModuleDBRootID1-3-3>

Node 2:
<ModuleDBRootID1-1-3>1</ModuleDBRootID1-1-3>
<ModuleDBRootID1-2-3>3</ModuleDBRootID1-2-3>
<ModuleDBRootID2-1-3>2</ModuleDBRootID2-1-3>

2.
Not allow read/write status for 2 nodes.

which is caused from master detection , that 2 master exists.

Example:

"10.233.52.40": {
"dbrm_mode": "master",
"10.233.53.237": {
dbrm_mode": "slave",
"10.233.52.110": {
dbrm_mode": "master",
