1.7.0
### Motivation Generally we want to inform users that they need to shutdown their HTTPClient. Until `1.6.0` we did this with an assert in HTTPClient's deinit. With `1.6.0` this behavior was raised to a precondition. Because of this adopters might suddenly crash in production where they didn't before. ### Changes - This pr reverts the current behavior back to something pre `1.6.0` ### Result - HTTPClient doesn't crash in production anymore.
