> In order to prevent race conditions when multiple client try to mutate the same column
before sending the request to mutate the column to the server do a checkAndMutate with the
column name being added/dropped. Also:
>  1. When a view is created do a checkAndMutate with the columns in the view where clause.
>  2. When an index on a view is created do a checkAndMutate with the indexed columns.
>  
> To prevent a race condition in the DROP TABLE CASCADE case, when a table is dropped do
a checkAndMutate with the rowkey of the base table name. If a view is created it also does
a checkAndMutate with the same rowkey.
