> Improve handling of 2i initialization failures

> Components: Feature/2i Index

> CASSANDRA-10130 fixes the 2i build management, but initialization failures
> are still not properly handled, most notably because:
> * Initialization failures make the index non-queryable, but it can still be
> written to.
> * Initialization failures can be recovered via full rebuilds.
> Both points above are probably suboptimal because the initialization logic
> could be more complex than just an index build, hence it shouldn't be made
> recoverable via a simple rebuild, and could cause the index to be fully
> unavailable not just for reads, but for writes as well.
> So, we should better handle initialization failures by:
> * Allowing the index implementation to specify if unavailable for reads,
> writes, or both.
> * Providing a proper method to recover, distinct from index rebuilds.
