Expose size of the indexes among statistics

Description

It is very useful for people to be able to monitor the overall size of the index.

People could normally monitor storage space for filesystem based indexes, but it's not that simple for other index storage options so we should provide a consistent metric, to be exposed as other statistics (mbeans).
