Change config mechanisms

[nicobarray]

It would be great to have a single file config.js foreach projects that gather the initialization of every process.env variables.

Here is an exhaustive list foreach projects:

• aquedux-server:

  • [ ] AQUEDUX_REDIS_PORT
  • [ ] DB_PORT_6379_TCP_PORT
  • [ ] AQUEDUX_REDIS_HOST
  • [ ] DB_PORT_6379_TCP_ADDR
  • [ ] AQUEDUX_SECRET
  • [ ] AQUEDUX_BUNYAN_LEVEL

• aquedux-client:

  • [ ] REACT_APP_AQUEDUX_BUNYAN_LEVEL

Env var should be replaced by explicit options on Aquedux creation/instanciation.

Other configuration steps like setReduceStateToQueueSnapshot should be done similary.
