Allow Bond Redemption to be vested and pooled

The current system allows for the protocol to be manipulated by bond holders in such a way that the moment the bonds become available for purchase, bots immediately redeem as many bonds as possible with a high gas price and further whales that do hold bonds; dump right away hence making it harder to cross the1$ mark.

AIP1 suggests that we vest all bond redemption rewards so that there is no dumping that happens the moment the bonds are made available

AIP3 suggests that bonds redemptions should happen as a pool; Pooling allows redemptions to happen in a more fairer way and further removes the chance of having gas wars since it is no more a First-come-first-serve model.
