* Move DoRequest* to godo package with stdlib context
* Use stdlib context package in place of godo context.
* Remove Go 1.6 from TravisCI configuration.
* Use stdlib context in util and tests instead of godo context.
* Add in Go 1.8, 1.9, and 1.10 to TravisCI configuration.
* Put 1.10 in quotes.
This patch updates the godo package to use a portable Go context -- a
Context that works with Go versions prior to Go 1.7 as well as Go 1.7
and onwards.

When adding options to a path, don't drop existing keys. This will enable image pagination when there is a type key to work. The bug was trying to addOptions to an existing path with query values. Previously if a path `/path?type=alpha` was passed, key `page=2` would be appeneded, but `type=alpha` would be dropped.
This makes it possible for consumers of the package to debug API calls made to the DO APIs.
Usage:
client.OnRequestCompleted(func(req *http.Request, resp *http.Response) {
// ... e.g. use httputil.DumpRequest / httputil.DumpResponse
})
