This PR introduced a change to how a specific group of characters are encoded client side, i.e. the colon character . This change is configured via a boolean field called rawHttpLabelValues and the default value is set to false. This means a change from existing behavior.
Additionally, an accompanying server side implementation for decoding was not provided, and therefore when utilizing a Smithy4s client and server together with the default behavior will result in breakage when encountering one of those characters in the URI path

Per discussion with @kubukoz , suggested plan is.

• mark the recent release 0.18.40 as broken in the Scala Steward repo
• subsequent pr set default for http clients to be true , and aws clients to be false. Create release after merge to rectify release
• another pr adding server side decoding determined by the same parameter
