[NO ISSUE][STO] Introduce ILSMIndexCursor

- user model changes: no
- storage format changes: no
- interface changes: yes
  - introduce ILSMIndexCursor as a sub interface for IIndexCursor
  - move getFilterMinTuple and getFilterMaxTuple to the
    ILSMIndexCursor interface.

details:
- IIndexCursor.getFilterMinTuple and IIndexCursor.getFilterMaxTuple
  don't make sense for any non LSM cursor and all the existing
  implementations return null for those calls.
- In this change, we move those methods to a new interface for
  LSM Index cursors.
