Add flattenthreads experiment
This experiment allows users to flatten the replies in threads, so they
are shown linearly in a chronological way instead of nested.
When the option is enabled, a switch is added to the thread page which
lets the user switch between flattening replies and not flattening them.
Some UI is still missing (see the design document[1]).
