Previously, AopAutoConfiguration would only enable CGLib-based
proxies if aspectjweaver was on the classpath. The intention was for
CGLib-based proxies to always be used by default so this behaviour
was incorrect.

This commit updates AopAutoConfiguration to force the use of
CGLib-based proxies even in the absence of aspectjweaver.

Previously, the endpoint tables in the documentation include an
"Enabled by default" column that listed whether or not an endpoint
was enabled by default. This resulted in some confusion as an endpoint
could be listed as being enabled by default but not actually be
enabled as the requirements for it being auto-configured has not been
met.

This commit removes the "Enabled by default" column and replaces it,
where needed, with some extra information in the "Description"
column that describes what is needed for the endpoint to be
auto-configured.

In 2.2.0, @ConfigurationPropertiesScan was enabled by default.
Unfortunately, this had the unexpected side-effect of breaking
conditional enablement of a @ConfigurationProperties class via
@EnableConfigurationProperties if the @ConfigurationProperties class
was in a package covered by scanning.

This commit remove @ConfigurationPropertiesScan from
@SpringBootApplication so that it is no longer enabled by default.
2.1.x users who rely upon such conditional enablement of
@ConfigurationProperties classes can now upgrade to 2.2.x without
having to make any changes. Users who do not have such a need and are
in a position to use configuration properties scanning can now opt-in
by adding @ConfigurationPropertiesScan to their main application class
alongside @SpringBootApplication.

Previously, all of the type exclude filters in
spring-boot-test-autoconfigure were package-private. This prevent a
user who was creating their own test slice from composing their own
TypeExcludeFilter with one of Boot's.

This commit updates all of the TypeExcludeFilters in the
test-autoconfigure module to make them public. The intention is only
to allow them to be composed with other type exclude filters when
referenced in a @TypeExcludeFilters annotation. Therefore, each
filter class is declared final and their constructors remain
package-private.
