Liquidator, liqtest and rust client fixes
- Make rust MangoClient fully async
- Update and improve liquidation test setup scripts
- Update liquidator to use versioned transactions
- Update liquidator to use mango and jupiter account lookup tables
- Use jupiter v4 api to get versioned transactions
Perp liquidation is still not fully good. See discussion aboult perp_liq_pnl_with_token.
Since Bank can't expand the existing OracleConfig, add a new one to Bank
and (temporarily!) copy over the old value to the new one in
TokenUpdateIndexAndRate.
Add some reserved space to OracleConfig to make this easier in the
future.
Breaks the PerpMarket and PerpPosition layouts
This adds three new options to perp markets:
- a flat fee, that is paid for all perp settlements
- given that they exceed the configured min settle amount threshold to
be eligible for fees
- and a fractional fee, that only applies when the benefiting account
has low health and gradually becomes bigger as the account slides
towards liquidation
