There was a lot of argument upstream about whether to keep 'hot_standby'
or 'archive' but after the proposal to change it to 'replica' came up
everybody seemed to fall in line with that.

+1 from me for using 'replica' as the WAL level to replace 'hot_standby'
and 'archive'.

+1 from me for removing the 'hot_standby' and 'archive' options entirely
in 9.6 rather than deprecating.

Unless anyone has objections I would like to mark this 'ready for
committer'.
