Remove http method from Base module.

[pkrawat1]

Refer stripe.ex

{api_key, ""} passing this parameter as empty string does not make sense here.

defp commit(method, path, params, opts) do
    config = Keyword.fetch!(opts, :config)
    # TODO: credentials should be investigated why it is {api_key, ""}
    # Did to mimic the earlier behaviour.
    method
      |> http("#{@base_url}/#{path}", params, credentials: {config[:api_key], ""})
      |> respond
  end

Please do necessary investigation for this one and fix it.

Edit:

• Remove http and money utils from Base
• Remove random* methods from Bogus

There is no usage of the http method defined in base.ex.
Hence, I'm changing the purpose of this issue.
