[Feature request] Using multipath payments

[thefeli73]

When i rebalance i don't really care if only a % of what i try to rebalance makes it over, so the rebalance would not need to be atomic. I therefore wish the program could attempt a flood type payment (like pickhardt uses) to send many payments.
Eg. i want to rebalance 1m sats, rebalance-lnd then attempts hundred 10k payments (possibly ignoring nodes that dont have #zerobasefee) over many different routes, the routes that succed can be used to attempt to send all the 'packets' that failed.
Currently i rebalance with small amounts and have to manually do it many times, since small amounts easily find cheaper routes

Closing issue because this is a duplicate, oops. I would however like some more automation, like "--repeat 10" to do a rebalance x times, saving me from having to watch the terminal untill the thing is done and the run the same command again, rinse repeat
