Update `MavenPublishingConventions` to add a new `mavenOptional` feature
that allows us to declare optional dependencies that are also published
in the generated POM.
This change allows us to include the maven-shade-plugin in the
spring-boot-maven-plugin POM which fixes an issue with Eclipse m2e.
Fixes gh-21992
This commit adds a new `spring.netty.leak-detection` configuration
property that selects the level of memory leak detection for the Netty
engine.
This configuration is applied statically to Netty; this means all
(non-shaded) Netty usages as client or server will be impacted by this
change.
Developers might use this property during development or tests to find
causes of memory leaks when dealing with Netty buffers.
Closes gh-14338
Previously, the auto-configuration for DataSource initialization and
the properties used to configure it were part of the general
DataSource auto-configuration and properties.
This commit moves the auto-configuration of DataSource initialization
out into a separate top-level auto-configuration class. Similarly,
the properties for configuring DataSource initialization have been
moved from `spring.datasource.*` into `spring.sql.init.*`.
The old initialization-related `spring.datasource.*` properties have
been deprecated but can still be used. When they are used, they new,
separate initialization auto-configuration will back off. In other
words, the initialization related `spring.datasource.*` properties
and the `spring.sql.init.*` properties cannot be used in combination.
Closes gh-25323
