question about default read/write to master or follower

[vhu...@reflektive.com]

if i have a setting like this in the initializer file, will all read/write with AR default using master?

```

  Octopus.environments        = [Rails.env]

  Octopus.config[:replicated] = true

  Octopus.config[:fully_replicated] = false

  Octopus.shards = {

    followers: follower_shards,

    master: ActiveRecord::Base.connection.config

  }

```
