This commit restricts how wildcards can be used in search
locations for property files. If a search location contains
a pattern, there must be only one '*' and the location should
end with a '*/'. For search locations that specify the file
name, the pattern should end with '*/<filename>'.
The list of files read from wildcard locations are now sorted
alphabetically according to the absolute path of the file.

Previously, the developmentOnly configuration, typically used for
Devtools, had to be declared manually. The BootJar and BootWar tasks
then had a property, excludeDevtools, that could be used to control
whether or not Devtools would be excluded from the executable archive.
This commit updates the reaction to the Java plugin being applied to
automatically create the developmentOnly configuration. The classpaths
of bootJar and bootWar are then configured not to include the contents
of the developmentOnly configuration. As a result of this, the
excludeDevtools property is no longer needed and has been deprecated.
Its default has also been changed from true to false to make it easy
to opt in to Devtools, when configured as a development-only
dependency, being included in executable jars and wars by adding
developmentOnly to the classpath of the archive task.

This commit removes the support for Reactor Netty metrics since it
seems that Spring Boot should not use this feature:
* HTTP metrics are already covered by WebFlux
* TCP metrics are only meant to TCP server/clients
* allocator metrics are already provided by Netty and there is
no specific API to enable them here.
Closes gh-19388
This commit enables the production of TCP and buffer allocator metrics
for Reactor Netty, client and server.
When applications use auto-configured server
(`NettyReactiveWebServerFactory`) and client (through
`WebClient.Builder`) instances, metrics will be enabled.
Note that HTTP metrics are not enabled here, since similar metrics are
already produced at the WebFlux level. Also, to avoid cardinality
explosion of metrics (through the URI tag), Reactor Netty offers
configurable infrastructure to deduplicate URI tags by turning expanded
URI instances into templated URIs. This is not targeted for Spring
usage.
Closes gh-19388
Improve "@ConfigurationProperties vs. @Value" documentation with the
recommendation that kebab-case is used with the `@Value` annotation.
Closes gh-20507
When using constructor binding, if no properties are bound to
a nested property, the top-level instance will be created with a
null value for the nested property.
This commit introduces support for an empty `@DefaultValue` which
indicates that an instance of the nested property must be created
even if nothing is bound to it. It honors any `@DefaultValue`
annotations that the nested property might have in its constructor.
