CASSANDRA-18714-5.0

both builds are totally clean, multiplexer too, I will focus on trunk now.

> {{CQLSSTableWriter}} currently has no way of writing any secondary indexes 
> inline as it writes the core SSTable components. With SAI, this has become 
> tractable problem, and we should be able to enhance both it and 
> {{SSTableImporter}} to handle cases where we might want to write SSTables 
> somewhere in bulk (and in parallel) and then import them without waiting for 
> index building on import. It would require the following changes:
> 1.) {{CQLSSTableWriter}} must accept 2i definitions on top of its current 
> table schema definition. Once added to the schema, any {{ColumnFamilyStore}} 
> instances opened will have those 2i defined in their index managers.
> 2.) All {{AbstractSSTableSimpleWriter}} instances must register index groups, 
> allowing the proper {{SSTableFlushObservers}} to be attached to 
> {{SSTableWriter}}. Once this is done, SAI (and any other SSTable-attached 
> indexes) components will be built incrementally along w/ the SSTable data 
> file, and will be finalized when the newly written SSTable is finalized.
> 3.) Provide an example (in a unit test?) of how a third-party tool might, 
> assuming access to the right C* JAR, validate/checksum SAI components outside 
> C* proper.
> 4.) {{SSTableImporter}} should have two new options:
>     a.) an option that fails import if any SSTable-attached 2i must be built 
> (i.e. has not already been built and brought along w/ the other new SSTable 
> components)
>     b.) an option that allows us to bypass full checksum validation on 
> imported/already-built SSTable-attached indexes (assuming they have just been 
> written by {{CQLSSTableWriter}})
