LP v2: `CentrifugeRouter` integration

[hieronx]

All investment interactions should now go through the CentrifugeRouter contract.

• [x] lp.requestDeposit => CentrifugeRouter.multicall([enable(), requestDeposit()])
• [ ] lp.requestDepositWithPermit => CentrifugeRouter.multicall([enable(), permit(), requestDeposit()])
• [ ] lp.mint => CentrifugeRouter.claimDepositRequest
• [ ] lp.requestRedeem => CentrifugeRouter.requestDeposit
• [x] lp.withdraw => CentrifugeRouter.claimRedeemRequest
• [x] lp.cancelDepositRequest => CentrifugeRouter.cancelDepositRequest
• [x] lp.claimCancelDepositRequest => CentrifugeRouter.claimCancelDepositRequest
• [x] lp.cancelRedeemRequest => CentrifugeRouter.cancelRedeemRequest
• [x] lp.claimCancelRedeemRequest => CentrifugeRouter.claimCancelRedeemRequest

[sophialittlejohn]

should these be the following instead of what's in the ticket above:

• [x] lp.withdraw => CentrifugeRouter.claimRedeem
• [x] lp.requestRedeem => CentrifugeRouter.requestRedeem
• [x] lp.mint => CentrifugeRouter.claimDeposit

Yep @sophialittlejohn good catches!
