Update LogbackLoggingSystem to clear logback status messages on reset.
This prevents shutdown errors from preventing subsequent startup.

Fixes gh-3472

Also add a test that I’d written before Phil fixed the problem in
5dbe6232.

See gh-3468

Switch JooqProperties.sqlDialect from a String to the actual enum to
allow IDE hints and case insensitive binding.

Fixes gh-3468

Move the Redis JUnit @Rule so that it can be used with
SessionAutoConfigurationTests. Also refactored the internals a little.

Without this change there can be more than one ServerProperties in a
context with different names.

Fixes gh-3476

See gh-3288

Never inject a transaction manager (user can create his own
"rabbitListenerContainerFactory" bean if he wants an actual
non-JTA transaction manager.

See gh-3432

If set *and* there is a transaction manager in the context, then the
listener container created by Spring Boot will use the transaction
manager to execute the listeners.

Fixes gh-3432 (by virtue of not requiring a JtaTransactionManager any
more).

When Spring Security sends 302 responses to a login page we don't get
any information about the request matching in Spring MVC. Consequently
apps can end up with a lot of counter.status.302.* metrics (where
"*" can be whatever the user sent).

This change treats 3xx the same as 4xx (if it is unmapped it just gets
added to a metric called "unmapped" instead of using the actual request
path).

Fixes gh-2563

See gh-3457

Liquibase has a `changeLog` property that is definitely used as a
`Resource` but cannot be defined as such as the original String value
should be kept against an API we don't control.

Update the tests also to make it more clear that if hints are added
against a property that is detected automatically, said property still
keeps all its auto-discovered capabilities.

Closes gh-3457

Add a new `spring-boot-configuration-metadata` module that provides an
API to manipulate Spring Boot configuration meta-data. Can read meta-data
from arbitrary locations, though the standard
`META-INF/spring-configuration-metadata.json` location must be preferred.
