config+server: add ignore-historical-filters CLI option

Browse Source 
This commit adds the ignore-historical-filters CLI option, initially
defaulting to false. Users may use this option to prevent lnd from doing
historical gossip dumps to peers that set their `gossip_timestamp_range`
in the past. Enabling this option will result in lower bandwidth and
memory consumption. Down the road the plan is to make this default to
true.
