Refactor validation for better readability

**Description**
Currently services lacks proper compression support.

**Proposed solution**
Add configurable compression with sensible defaults.

**Priority**: Low/Medium

Start by locating the services and validation code responsible for the currently unsupported compression behavior. Check how service configuration and defaults are handled, then define the supported configuration and verify that compressed service traffic works with sensible defaults; the issue names no files or tests, so the relevant entry points must be identified first.
