OpenSSL::SSL::SSLError on Heroku

[sunny]

When using Heroku’s default stack, using this gem generates an SSL error.

This is due to Ruby not being able to find the certification authority certificates (CA Certs) used to verify the authenticity of the request.

To fix it, you can add the following:

OpenWeather.configure do |config|
  config.ca_file = ENV["OPENWEATHER_API_CA_FILE"] if ENV["OPENWEATHER_API_CA_FILE"]
end

And configure the path to the CA certificate on Heroku:

heroku config:set OPENWEATHER_API_CA_FILE=/usr/lib/ssl/certs/ca-certificates.crt

I believe we need a fix like slack-ruby/slack-ruby-client#416 here. Want to contribute it @sunny?

Thanks for the swift reviews and merges!
