performance/write-behind: add option "enable-trickling-writes".

- With this option enabled, writes are stack-wound even though not enough
    data is aggregated, provided there are no write-requests which are
    stack-wound but reply is yet to come. The reason behind this option
    is to make use of the network, which is relatively free (with no writes
    or replies in transit). However, with non-standard block-sizes of writes
    the performance can actually degrade. Hence making this configurable.
