PS6, Line 488: changeImmutable

There are some difference in the implemention and usage between Java and C++. 
In C++, adding column and altering column share the same KuduColumnSpec, it's 
actually convenient to create and alter a table like:

builer.AddColumn("imm_val")->Immutable()->Type(...)->...;
table_alterer->AlterColumn("int_val")->Immutable();

but in Java, they are separeted, using ColumnSchemaBuilder and 
AlterTableOptions. Here, using 'changeImmutable' is also to keep the same style 
with other functions in AlterTableOptions, like 'changeComment', 
'changeEncoding', and etc.
