Refactor Layer2 Pool Token Mechanics and Bonding Logic

[kmlbgn]

Description

The current pool logic for dApp is wrong: the dp tokens (dApp tokens) do not exist, are never minted, and are not paired against the KEX tokens (similar to Uniswap v2 pools).

Expected Behaviour

A big refactor is needed for Layer2

• total_bond parameters should be renamed to pooled_kiratoken
• ratio should be renamed to supply_init, which corresponds to the initial supply of dp/token to be minted when RollApp proposal passes.
• supply_cap parameter should be added (since token minting will use the minting module Migrate Minting module from Layer 2 module to Token Module and Refactor Token Module Structure #664). It can accept 0 value. It cannot be set below supply or transaction fails.
• pooled_dapptoken parameters must be added to contain minted dp/denom
• pooled_kiratoken, pooled_dapptoken and supply_init should be integrated into a LiquidityPool param of dApp object.
• Missing dapp_pool_fee Network Property  #674 should be resolved ,pool_fee parameter must be deleted from dApp object
• LpPoolConfig object should be deleted, only IssuanceConfig is relevant.
• IssuanceConfig must contain drip, deposit, postmint, premint, premint_time, postmint_time parameters (ratio belongs to LiquidityPool object).
• Refactor Layer2 Issuance and Vesting Logic  #676 should be resolved
• Appropriate amount of dp/<denom> should be minted using supply_init at the same time as lp/<denom>, and put into LiquidityPool.pooled_dptoken against the bonded KEX.
• Redeeming LP tokens should give back the pooled KEX and dpTokens in amounts at a 50/50 ratio, calculated with the bonding curve formula similar to how Uniswap v2 works X x Y = K.
• A redeem-dapp-pool CLI command should be implemented to lock dp tokens/KEX tokens, according to the bonding curve similarly to Uniswap v2.
• All redeem-dapp-pool, swap-dapp-pool, and convert-dapp-pool must be refactored since they should transact with dp/token. Refactor convert-dapp-pool and add CLI for Cross-App LP Token Swapping #678
• bin: version parameter is missing #677 must be resolved
