Introduce an alternative autoconfiguration if the lettuce Redis driver is
available. Add Lettuce-specific configuration property options
"spring.redis.lettuce.shutdown-timeout" to control the shutdown timeout
of the lettuce driver. Add documentation for the properties, the
supported drivers, and how to switch between drivers.
Split client-specific properties from spring.redis.pool to
spring.redis.jedis.pool and introduce spring.redis.lettuce namespace.
Deprecate spring.redis.pool property.

CachePublicMetrics wasn't explicitly tested and was still using field
injection. This commit improves the situation in preparation of the fix
for gh-8984
Update `SpringApplicationBuilder` so that the `sources(...)` method
updates the primary sources. Prior to this commit, the fix for #8910
had the unfortunate side effect of stopping the
`SpringApplicationBuilder` from being used with
`spring.application.main` properties.
Fixes gh-9053
Update `ConfigurationPropertySourcesPropertySource` to no longer use
`try/catch` when checking for valid names. A new `isValid` method has
been introduced to `ConfigurationPropertyName` which is offers better
performance.
Fixes gh-9058
Update the `Binder` to short circuit potentially expensive bean binding
if there are no known child properties. The shortcut can only be applied
when all used `ConfigurationPropertySources` return a non empty
`containsDescendantOf` result. This should be the case for most
Spring Boot applications, the exception being any apps that are running
in a security restricted environment.
Fixes gh-9023
Update `ConfigurationPropertySource` with a `containsDescendantOf`
method that can be used to tell if a source contains any descendants
of the given name.
The result is Optional so that sources that cannot determine a result
may return `empty()`.
The existing `IterableConfigurationPropertiesSource` has a default
implementation that works by iterating the contained values. Most other
sources return `empty()` with the exception of the adapted
`RandomProperySource` with will return true for `random.*` names.
See gh-9023
Update `NoUnboundElementsBindHandler` to also support ignoring
nested properties. This change is required to allow the
`NoUnboundElementsBindHandler` to be used alongside the
`IgnoreNestedPropertiesBindHandler`.
See gh-9000
Create separate `IterableConfigurationPropertySource` and
`ConfigurationPropertySource` interfaces so that it's possible to
work out if a source can truly iterate the values that it contains.
Prior to this commit there was only a single
`ConfigurationPropertySource` interface, which returned an empty
Iterator when values could not be iterated. This design made it
impossible to tell the difference between a source that was empty, and
a source that could not be iterated.
The `ConfigurationPropertySources` class has been updated to adapt
non-enumerable and enumerable Spring PropertySources to the correct
`ConfigurationPropertySource` interface. It also deals with the edge
case of the `SystemPropertySource` running in a security restricted
environment.
Fixes gh-9057
Update `DefaultServletWebServerFactoryCustomizerTests` so that the Jetty
access log tests use the default timezone. Prior to this commit it was
possible that running the tests outside of UTC could result in Jetty
throwing a "negative delay" IllegalArgumentException.
See gh-8819
