feat(ibc): (1) IBC compatibility to app.go. (2) CLI enabled. (3) IBC tests. | Realu/ibc

[Unique-Divine]

Task Summary

• closes feat (ibc): Add IBC compatibility to app.go #244
• closes test(ibc): Packet transfer send, receive, and confirm #577
• closes test(ibc): BeginBlocker on local host client #578
• closes test(ibc): Test connection and light client initialization after blocks are committed #579

The CLI seems to work.

Integrating the IBC module

• Add required modules to the module.BasicManager
• Define additional Keeper fields for the new modules on the App type
• Add the module's StoreKeys and initialize their Keepers
• Set up corresponding routers and routes for the ibc module
• Add the modules to the module manager
• Add modules to Begin/EndBlockers and InitGenesis
• Update the module SimulationManager to enable simulations
• The capability module must be declared first in SetOrderInitGenesis

ibc-go testing TestingApp

• Adhere to ibc-go TestingApp interface so that we can plug this into integration tests.
• TestInitialization: Setup of clients, connections, and channels work
• TestClient_BeginBlocker: local host light client initializes properly and state increments properly after several blocks
