This commit combines security autoconfigurations for
management endpoints and the rest of the application. By default,
if Spring Security is on the classpath, it turns on @EnableWebSecurity.
In the presence of another WebSecurityConfigurerAdapter this backs off
completely. A default AuthenticationManager is also provided with a user
and generated password. This can be turned off by specifying a bean of
type AuthenticationManager, AuthenticationProvider or UserDetailsService.
Closes gh-7958
The default is now SecurityProperties.ACCESS_OVERRIDE_ORDER-1
(instead of 3), and the user can set it with
security.oauth2.resource.filter-order (as opposed to being hard
coded). The filter is provided by Spring OAuth2 so this change is
a BeanPostProcessor to call a setter on that object.
Fixes gh-5072
