A huge thanks to all the contributors for this release.

Changelog

• Concurrent checks for all the checkers. This should prove to decrease latency for healthcheck response if there are a bunch of checkers doing Network I/O.
• Optional global timeout for all checkers, in case you'd like to restrict the max response time. This includes context cancellation. This results in a breaking change since the checker requires the context to be passed for signalling cancellation. Thanks to @pcasaretto for working on this.
• Observers, which are non-essential checkers that do not need to result in healthcheck failure, but can be captured for error logging.
