Subject: [PATCH] allow-user-to-pass-env-variables-when-generating-docs

Why
This is to allow users to use environment variables in their `open_api.yaml` file.
Like so:
```
swagger: '2.0'
info:
  title: My Api
  description: About my api
  version: "1.0.0"
host: <%= ENV.fetch('host_name') %>
```
They could then call the generate command like:
```
host_name=env_specific_host.com rake docs:generate
```
This way someone can generate multiple different swaggers with different environemnts
