feat(trading-proto-upgrade): fees fixes among other things

[mariocynicys]

The main feat here is taker payment spend fee negotiation (I guess we will refactor namings in the swaps v2 code and rename this to taker payment fee/funding spend fee):

The negotiation goes as follows:

• Taker and maker each decide how much this fee should be at the beginning of the swap.
• The taker will send the maker their proposed fee during negotiation, if the maker deems the fee as low enough (less than 90% of the maker's own calculated fee), they will refuse to trade before the trade starts. Otherwise, they will continue and use this fee for validation later.
• The maker will validate that the taker has accounted for this fee in the funding transaction.
• The taker will validate that the taker payment preimage (generated by the maker) uses the negotiated fee or greater (greater number will deduct from the maker's trading volume anyway). If not, the taker will stop the trade since the maker is clearly stealing funds that isn't his which might affect the completion of the swap if the fee is low.

Proto v2 issue pool:

• was already fixed:
  • immediate taker refund using S2
  • accept_only_from our order peer.
• fixed in this PR:
  • use a u8 fork id
  • negotiate funding spend fee and let taker add it to the funding tx
• still missing:
  • research: concurrent conf
  • recover_funds_for_swap rpc for swaps v2
  • investigation of why test_taker_completes_swap_after_restart is flaky
  • other refactors

Fixmes & discuss comments are intended to be covered in the PR.
