♻️ Restructure Repo To Make Launching Adapter Contracts Easier

[NotJeremyLiu]

Background

• Previously, the contracts folder was separated by network, which ends up being not ideal since some adapter contracts (for example, astroport swap adapter) can be launched on multiple chains.
• Thus, chain separation should happen at the deployment level, and not the contract organization level

This PR:

• Groups the adapter contracts by adapter type, leaving the network organization to the deployment scripts
• Resulting in a restructure of the repo from:

│
├── contracts/              <- Contains all contracts
│   ├── entry-point/        <- Contains source code and tests for entry point contract
│   └── networks/           <- Contains source code and tests for all network adapter contracts
│       ├── neutron/
│       │   ├── ibc-transfer/
│       │   └── swap/
│       └── osmosis/
│           ├── ibc-transfer/
│           └── swap/

to:

│
├── contracts/              <- Contains all contracts
│   ├── entry-point/        <- Contains source code and tests for entry point contract
│   └── adapters/           <- Contains source code and tests for all network adapter contracts
│       ├── ibc/
