Since Spring Framework 4.3.0.RC2, a default embedded value resolver
has been registered with the bean factory when one is not otherwise
configured. This meant that placeholders in `@Value` would be resolved
with or without PropertyPlaceholderAutoConfiguration defining a
PropertySourcesPlaceholderConfigurer bean. However, placeholders in
bean definitions would only be resolved if a
PropertySourcesPlaceholderConfigurer was defined.

This commit updates PropertyPlaceholderAutoConfigurationTests to align
with this change in Framework. We now test that placeholders are
resolved in `@Value` annotations with or without the auto-configuration
and that placeholders in bean definitions are only resolved with the
auto-configured.

Previously, if TomcatMetricsBinder destroy() was called before it had
received an ApplicationStartedEvent an NPE would be thrown due to
TomcatMetrics being null. This NPE was then caught and logged at
warning level by the disposable bean adapter.

This prevents the NPE by checking that the TomcatMetrics instance is
null before calling close() on it.

Previously, the thread dump endpoint's response could exceed
WebClient's in-memory buffer limt when there were a large number of
threads or the threads had large stacks.

This commit disables WebClient's in-memory buffer size limit so that
the test passing is not dependent on the number of active threads and
their stack sizes.

Prior to Spring Data Redis version 2.2.8, the contents of the
Properties object returned from the
ReactiveRedisConnection.ServerCommands.info API were the same
for clustered and non-clustered Redis configurations, containing a set
of key/value pairs. This allowed ReactiveRedisHealthIndicator to get
a version property using a well-known key. Starting with Spring Data
Redis 2.2.8, the info property keys contain a host:port prefix in a
clustered Redis configuration. This prevented
ReactiveRedisHealthIndicator from getting the version property as
before and resulted in the health always being reported as DOWN.

This commit adjusts ReactiveRedisHealthIndicator to detect the
clustered configuration from Spring Data Redis and find the version
property for one of the reported cluster nodes.

Rework the inheritance so that the property metadata JSON more

Update `Group` properties so that the `showDetails` value does not
inherit `Show.NEVER`. Prior to this commit, the `Group` properties
would not correctly inherit a `showDetails` value from the main
`management.endpoint.health.show-details` property.
