Added homepage, docs, and repo to Cargo files (#6)

* Updated header values for provided runtime and switched to ms time remaining

* Fixed issue with deadline not being set in context and switched to realtime clock to get correct epoch

* Removed libc dependency and switched to chrono for deadline calculation

* Fixed docs example not to import HttpRuntimeClient

* New error reporting method with correct content type and error type header.

* Two fixes to honor max retries in the get_next_event method and call the error_reponse rather than init_fail when an error is thrown after the call to /next

* Added homepage, docs, and repo to Cargo files
