Sleuth causes early initialization of numerous beans, preventing them from being ServletContextAware

[wilkinsona]

When Sleuth is used in a Servlet-based web application that's using Boot's Actuator, creation of sleuthSkipPatternProvider causes every endpoint bean and their dependencies to be initialized very early, and crucially before the servlet context is available. This results in the ServletContextAware contract not being honoured causing subsequent failures in Spring MVC.

Please see spring-projects/spring-boot#28952. It contains a description of the problem, a sample that reproduces it and some initial analysis that led to the creation of this issue.
