This commit adds support for Spring Boot error conventions with WebFlux.
The Spring MVC support for that is based on an `Controller` that's
mapped on a specific `"/error"` path and configured as an error page in
the Servlet container. With WebFlux, this support leverages a
`WebExceptionHandler`, which catches exceptions flowing through the
reactive pipeline and handles them.
The `DefaultErrorWebExceptionHandler` supports the following:
* return a JSON error response to machine clients
* return error HTML views (templates, static or default HTML view)
One can customize the error information by contributing an
`ErrorAttributes` bean to the application context.
Spring Boot provides an `ErrorWebExceptionHandler` marker interface and a
base implementation that provides high level constructs to handle
errors, based on the Spring WebFlux functional flavor.
The error handling logic can be completely changed by providing a custom
`RouterFunction` there.
Fixes gh-8625
Previously, the custom layout sample did not configure the source
and target for the compiler. This meant that both defaulted to 1.5
which is not supported by Java 9's javac. The oldest support version
is 1.6.
This commit sets the maven.compiler.source and maven.compiler.target
properties to 1.8 (the lowest version support by Boot 2.0) allowing
the sample to build with both Java 8 and Java 9.

Provide informative reason when rejecting request with invalid level
Previously, bad request with no reason was included in the response.
This commit introduces the reason when invalid log level is sent in the
request.
Fixes gh-10588
Previously, rolled over files were always written to logs/. This
commit ensures that rotated logs are written into the directory
specified in the application config's logging.path property.
