There are places in which we need to use the column family object many
times, with deferring points in between. Because the column family may
have been destroyed in the deferring point, we need to go and find it
again.
If we use lw_shared_ptr, however, we'll be able to at least guarantee
that the object will be alive. Some users will still need to check, if
they want to guarantee that the column family wasn't removed. But others
that only need to make sure we don't access an invalid object will be
able to avoid the cost of re-finding it just fine.

This patch replaces the helper function for column family with two
function, one that collect the relevant column family from all shareds
and another one that do the translation to json object.

Some APIs other then the column_family need to use the get_cf_stats,
this adds the helper method decleration to the column_family.hh and
change the implementation decleration to be non-static

This adds the API implementation to the column family API.
After this patch the following API will be supported:
/column_family/name
/column_family
/column_family/name/keyspace
