   …xes from server to client
   
   This PR moves the column combining logic from the server to the client. For older clients since the child view metadata included the parent column metadata as well when we return the ```PTable``` from the server it will already include parent table column metadata. 
   I moved the add and drop column code in ```MetadataEndpointImpl``` that was present in anonymous classes that implemented ```ColumnMutator``` into their own classes  ```AddColumnMutator``` and ```DropColumnMutator```. 
   I also renamed ```ViewFinder``` to ```ViewUtil``` and moved the column combining logic from ```MetadataEndpointImpl``` and the code that adds indexes from parent tables from ```MetadataClient``` to this util.
