With this commit we remove the three previously unused Netty 4 related settings
transport.netty.max_cumulation_buffer_capacity
,transport.netty.max_composite_buffer_components
andhttp.netty.max_cumulation_buffer_capacity
from Elasticsearch.As this is a breaking change (we remove settings), I'd like to get this in for 6.0, otherwise we need to keep them around until 7.0. However, as they were unused (and undocumented) previously I think the risk is low.
