UI/API check

1-Add cluster using  API addCluster

add cluster API should have new parameters  cpuovercommitratio and ramovercommitratio

 

 

 

 

 

 

 

 

 

UI/API check

1- Fire API UpdateOvercommitRatio with parameter cpuovercommitratio,ramovercommitratio.

response should contain " details of the updated cluster along with the overcommit ratios"

 

 

 

 

 

 

 

 

 

DB check

1-Logoin through UI
2-create a cluster with overcommit factor x
3-Login to DB
4-check cluster detail table

1-There should be some attribute ,which  represent overcommit factor and should have store overcommit factor for the clusters .
