feat: Enable warp route chain connection customization

[ltyu]

Problem

Currently, we assume all chains are connected during deployment. However, we may have cases where we want to customize how the chains are connected. For example, Zerion's multicollateral warp route needed routes to only go between Zeronetwork and other chains

Solution

• Use WarpConfig.remoteRouter to express connections. currently, it is only populated by warp read.
• Consider prompting the users via the CLI (needs design)
