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.

This commit changes the information provided by
RedisReactiveHealthIndicator to include cluster details when Spring
Data Redis detects that Redis is running in a clustered configuration.
This brings the reactive and non-reactive Redis health indicators
into alignment.

Fixes gh-21514

Closes gh-22095

Fixes gh-22061 in 2.3.2

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.

* pr/22022:
  Polish 'Inherit show-details property in health groups'
  Inherit show-details property in health groups

Closes gh-22022

Rework the inheritance so that the property metadata JSON more
accurately reflects the default value.

See gh-22022

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.

See gh-22022

Rename `ImageReferenceParser` to `Regex` and remove state. The regular
expressions are now used directly by the `ImageName` and
`ImageReference` classes with the values accessed directly from the
`Matcher`.
