closes https://github.com/paritytech/polkadot-sdk/issues/158. partially addresses https://github.com/paritytech/polkadot-sdk/issues/226. Instead of fragile calculation of current balance by looking at `free balance - ED`, Nomination Pool now freezes ED in the pool reward account to restrict an account from going below minimum balance. This also has a nice side effect that if ED changes, we know how much is the imbalance in ED frozen in the pool and the current required ED. A pool operator can diligently top up the pool with the deficit in ED or vice versa, withdraw the excess they transferred to the pool. ## Notable changes - New call `adjust_pool_deposit`: Allows to top up the deficit or withdraw the excess deposited funds to the pool. - Uses Fungible trait (instead of Currency trait). Since NP was not doing any locking/reserving previously, no migration is needed for this. - One time migration of freezing ED from each of the existing pools (not very PoV friendly but fine for relay chain).
