prepare to delete METProducer

[TaiSakuma]

In #1745, six dedicated new producers to replace METProducer were merged.

In #1936, HLT configuration started using CaloMETProducer, one of the new dedicated producers, instead of METProducer.

This pull request replace further remaining METProducer with new dedicated producers.

After this request is merged, I think then we can actually delete METProducer.
