Faraday dependency minimum should be 1.0

[matt-eaton]

Not sure what is involved in setting a minimum dependency for Faraday. I think this line here:

spark_api/lib/spark_api/faraday_middleware.rb

Line 33 in 0c8b5df

CGI.parse(env[:request_body])

Will require Faraday 1.0.

This looks like the PR into the 1.0 release that adds the functionality to support "request_body".

spark_api/lib/spark_api/faraday_middleware.rb

Line 33 in 0c8b5df

CGI.parse(env[:request_body])
