kailiu 66dc033af3 Temporarily disable caching index/filter blocks
Summary:
Mixing index/filter blocks with data blocks resulted in some known
issues.  To make sure in next release our users won't be affected,
we added a new option in BlockBasedTableFactory::TableOption to
conceal this functionality for now.

This patch also introduced a BlockBasedTableReader::OpenOptions,
which avoids the "infinite" growth of parameters in
BlockBasedTableReader::Open().

Test Plan: make check
