Evil Accounts spammer

[daria305]

TODO:

• [x] extend transaction builder in iota.go with accounts
• [x] simple account spammer, we create new accounts from faucet funds, we do not handle those accounts
• [ ] evil spammer should allow to create account and remember it for further usage, and spams
• [ ] solve bootstrapping with implicit account
• [x] account handling tools separated from evil spammer, like go run . accounts
• [x] solution to keep the state with basic spammer, it creates wallet.dat file storing the wallet state
  • both accounts tool and evil spammer use the same accountsWallet read from wallet.dat file so we can
• [ ] created account that can be used with previous functionality of evil spammer, with alias name we provide in options what account should be used for each spam:
  • go run . accounts --create A --amount 100000
  • go run . basic --spammer tx --rate 2 --duration 60s --issuer A <- here we will use mana from account
• [x] make sure mana is not lost during block creation for evil spammer: AllotRequiredManaAndStoreRemainingManaInOutput might be useful
• [ ] handle allotment strategies to pay for block issuance:
  • allot exact burnt mana cost, use BuildAndSwapToBlockBuilder
  • changing allotment amount, testing negative BIC balance
  • allot in advance for data payload spam
• [ ] handle other block types: validation blocks

Evil spammer fixes:

• [x] adapt to new outputID calculation principles
• [ ] calculate the target number of required funds and handle funds requesting for longer spams, in RequestFreshBigFaucetWallet and similar functions

Fix issues regarding REST API:

• [x] fix RMC endpoint nil reference error
• [x] BlockMetadata endpoint and providing statuses does not work properly, need it for Awaiting ForConfirmation functionality of evil spammer
• [x] Add slotIndex to BlockIssuer endpoint to point to specific slot we need the commitment for, so that respnce from congestion endpoint always matches

Example of planned script usage

./evil-spammergo \
accounts \
create --alias A --amount 1000 --noBIF true \ # noBIF - creates account that is not able to issue
create --alias B --amount 500 --implicit true \
convert --alias B \  # transition to account from implicit
allot --from A --to B --amount 100 \ # if no from then get mana from faucet output, from can be alias of existing account
update --alias B --bik hexkey --addmana 1000 --addtoken 1000 --expiryslot 15 \
destroy --alias A --expirySlot 15 \ # if no expiry then use soonest possible
...
delegate --amount 100 --to A --from B \# we dont keep track of non account outputs
stake  --alias A --amount 100 --fixedcost 100 --startepoch 100 --endepoch 120  \ # if no startepoch start sonnest possible epoch, no endEPoch then stake infinitely,

or togheter with evil spammer functionality

./evil-spammergo accounts \
create --alias A --amount 1000 --noBIF true \ # noBIF - creates account that is not able to issue
create --alias B --amount 500 --implicit true \
# use created above accounts
./evil-spammer basic  -spammer tx -rate 1 -duration 10s -account A
./evil-spammer basic  -spammer tx -rate 1 -duration 10s -account B
