Title: Cleanup boost optionals for boost 1.56

Cleans up errors with boost 1.56 such as

```
building ceph_filestore_dump
CXXLD ceph_filestore_dump
./.libs/libosd.a(libosd_la-ReplicatedPG.o): In function `operator<< , long unsigned int>':
/tmp/nix-build-ceph-0.85.drv-0/ceph-0.85/src/./include/types.h:91: undefined reference to `std::basic_ostream >& boost::operator<< , unsigned long>(std::basic_ostream >&, boost::optional const&)'
./.libs/libosd.a(libosd_la-ECBackend.o): In function `operator<<(std::ostream&, ECBackend::read_result_t const&)':
/tmp/nix-build-ceph-0.85.drv-0/ceph-0.85/src/osd/ECBackend.cc:84: undefined reference to `std::basic_ostream >& boost::operator<< , std::map, std::allocator > > >(std::basic_ostream >&, boost::optional, std::allocator > > > const&)'

```

This builds fine for me with ceph 0.85 and boost 1.56
