Change description of delayed_node option

[HarukaMa]

It seems that witness_node will populate all possible options to config.ini from all available nodes in new data dir, and the description of trusted-node for delayed node is a bit confusing.

It looks like:

# Will only store matched orders in last X seconds...
max-order-his-seconds-per-market = 2592000

# RPC endpoint of a trusted validating node (required)
# trusted-node =

# Block number after which to do a snapshot
# snapshot-at-block =

while it's not required for a normal node.

Maybe we should not merge this, instead prepend the name of plugin before corresponding options to clarify this (#1407).

Thanks.
I think we should accept the change for now, until we have a better solution for #1407

Please hold this merge, i am working in a solution for #1407 . Not very elegant but we can discuss it. Pull request for it coming in the next hours.

As #1411 would still take some time to come out, maybe this one should be merged first? I've seen another report of confusing comment in dev group just now...

I agree, the final solution was a lot harder than expected and this at least will avoid some confusion.
