Feature Request: add --ignore-forward-fees-below and --ignore-rebalance-fees-below

[zapomatic]

in addition to --ignore-forwards-below and --ignore-rebalances-below, for channels that have a zero fee, or very low fee (heavy source channels), a node operator might want to suppress getting alerted every time that channel receives funds, even if it's over the forwards-below threshold since it results in 0 (or close to zero) fees earned. Likewise, it would be nice to be able to ignore rebalances of even high amounts if the cost for those rebalances is under a certain threshold.

.option("--ignore-forward-fees-below <amount>", "Ignore forwards that earn fees below value", INT)
.option("--ignore-rebalance-fees-below <amount>", "Ignore rebalances that cost fees below value", INT)
