organizing deployments and dev process

This PR is really just prep work to introduce Indexter into our Jenkins CI. It includes a makefile that has a series of code quality checks such as unit testing, linting, static checks, and race conditions.

I also introduced the indexter.yml config as a config map in Kubernetes so we no longer need to bake a new image every time we want to switch the nodes and networks.

I also updated the prod currencies folder with the latest contracts.
