Previously, only UndertowOptions was used as the source of options for
both server and socket options, but it only contains server options.
As a result, attempting to configure any socket options defined by
XNIO's Options class would fail.

This commit updates the property-based configuration of options to use
UndertowOptions as the source for server options and XNIO's Options as
the source for socket options.

  Add generated-snippets as output to test goal

Closes gh-22555

See gh-22555

The generated snippets were not declared as an output to the
`spring-boot-actuator-autoconfigure` test goal so when the test was
pulled from the cache, it did not contain the `generated-snippets`
directory. This directory is required as an input to the Asciidoctor
plugin.
