== Goal
Remove indentation from response body for all services to decrease its size.
== Background
At this moment we are using `MarshalIndent` function to map the response body. This function is beautifying the response including some characters (new line and spaces) to make that response "human-readable". That increases the output size a lot (around 66% for some cases in geo). Because we don't really need at all this indentation, we can replace that function to use `Marshal` that maps the response body in a minified way (no indentation). Same response and less size.
== Tasks
Remove indentation from the response body (replacing the `MarshalIndent` function by `Marshal` in the `handler` layer and `healthz` endpoint) for the following services:
