SEC-2723: Add meta-data to bean definitions of Spring Security Filter beans identifying them as "inner"

[spring-projects-issues]

Dave Syer (Migrated from SEC-2723) said:

Add meta-data to bean definitions of Spring Security Filter beans identifying them as "inner", meaning that they have the Filter interface, but are not registered with the ServletContext (in retrospect maybe a different interface would have been better, but it's too late for that). The Filter beans created by Spring Security (with the exception of the global "springSecurityFilterChain"), and the ones added as custom filters, often trip up users of Spring Boot. If Spring Security could help us identify those beans it would make it easier to exclude them from the ServletContext.
