If the user sets security.basic.enabled=false we should just
back away from the non-management endpoints completely.
Previously the Spring Security filter was still added but with
no authentication, creating complications when unexpected
headers etc. are added by Spring Security.
Management endpoints are still secure by default if
Spring Security is present, but now the default
user details have an ADMIN role, and a random password
(which is logged at INFO level if not overridden).
To override you add management.user.password (name, role)
to external properties.
[Fixes#53029715] [bs-203]
* Add integration tests for /error view
* Add "error" @Bean as default view for HTML
Users may see side effects because now there will be
a ContentNegotiatingViewResolver by default for the
first time in a vanilla Actuator app. Should be
interesting.
