include headers in Strava::Errors::Fault response

[JamesChevalier]

Why:

• by including the headers, we have access to x-ratelimit-limit and x-ratelimit-usage

How:

• pass along the headers, similar to message and errors
• include the headers (as they exist in the current cassette) in the existing specs
• update the CHANGELOG.md file, as requested
• update the README.md file to include the existence of e.headers, and include a truncated example of its value

Relevant Links:

• Specialize rate limiting errors #11
• https://developers.strava.com/docs/#rate-limiting

Nice and easy.

You might still want to do #11 ;)

🤔 Do you think it's worth mentioning details about how to access the data in the README?

For example...
accessing the current usage:
quarterly_usage, daily_usage = e.headers["x-ratelimit-usage"].split(',').map(&:to_i)
and accessing the current limits:
quarterly_limits, daily_limits = e.headers["x-ratelimit-limit"].split(',').map(&:to_i)

👍 Yeah, I still want to get these details into each response. I don't have a lot of confidence in how I'll approach that, so that pull request probably won't be a quick merge like this. 😄

Definitely useful for a README, can't hurt.

You could wrap headers into a class and expose an additional method called x_rate_limit and expose limit and usage as first class objects, too.
