Required a rewrite of most of the logging throughout the app as the
correlation ID is added to the logger through context, which means we no
longer need to pass the logger around, but rather only reconstruct it
from context where needed.

The conditional required validation failure would not return the error
as a validation error making it more difficult to handle on the
frontend.

Resolves #30

Fixes a 500 error when the user would fail to provide a laptime or race
length

move it to the base strat test since the error check is there already

If stint laps result in 0, then the code further down will run into a
division by 0 and cause a panic. To avoid this, throw an error and
inform the user that they have an issue in the submitted data.

no stop is when we don't have a full stint, or when we have one full
stint, but no additional laps

if a race consists of one stint only, it is a no-stop strategy

each strategy might have different amount of required stops

makes things a bit less confusing if expectations on parameters is the
same across the board

This is focused soley on functionality and requires a refactor to get
rid of repeated code etc.

The Auth API has recently switched to a more secure shared-key signed
JWT to transmit user information to downstream services instead of a
plain JSON in order to allow the consumers to verify the token issuer.

The middleware checks if the user data is set in the headers same as
check auth but does not fail, so that endpoints using this middleware
can still process the request where auth is optional.

When a PUT request is made with empty file content do not overwrite the
empty contents into the file in the storage
