Because version 5.0.0 depends on elasticsearch 5.0.0 and we
apparently do not want this as per parent changeset.

same thing for --except_etype

[search_helpers] only use common and phrase searches, stop splitting up elements into multi_mach (canceled the common word stop work removal)

[es] don't try/except on index creation, now only used in ccplugin and scripts, fail hard so we can see the index settings errors

Otherwise we would overwrite the "mappings" entry

FTI update is now done at commit time in an operation,
we need to call commit() to trigger it

NOTE: I think it would be best if the elasticsearch didn't generate
any HTML at all.
