      During my work on a new compaction policies (HBASE-14468, HBASE-14477) I had to modify the existing code of a StoreFile.Writer to add additional meta-info required by these new policies. I think that it should be done by means of a new Plugin framework, because this seems to be a general capability/feature.

      As a future enhancement this can become a part of a more general StoreFileWriter/Reader plugin architecture. But I need only Meta section of a store file.

      This could be used, for example, to collect rowkeys distribution information during hfile creation. This info can be used later to find the optimal region split key or to create optimal set of sub-regions for M/R jobs or other jobs which can operate on a sub-region level.
