Update RunMojo to include an @Execute annotation. Allows the use of
`mvn spring-boot:run` without having to compile/package first. Now a
command like `mvn clean spring-boot:run` works.

The phase for @Execute annotation is along the lines of what is used
for the `jetty:run` plugin.

Update SpringIntegrationCompilerAutoConfiguration to use the managed
version of spring-integration-groovy-dsl.

Fix classloader issues by excluding spring JARs from test classpath
and also include spring-integration-groovy-dsl as a managed dependency.

Cleaned up file separators to prevent tests failing on Windows.

Update Launcher to correctly handle spaced in file paths.

Refactor JavaLoggerSystemTests to make use of OutputCapture and ensure
that captured output never includes ANSI symbols.

The spring property should have been spring.profiles.active instead of
spring.active.profiles.

Fix TomcatEmbeddedServletContainerFactory to set a MERGED_WEB_XML
attribute when JSPs are used. This is required for EL support with
JSPs since Jasper checks the version number in the web.xml. Without
any web.xml Jasper default to disabling EL.

Use standard class loading delegation with Tomcat.

Include resource mapping for web-jar resources.

Issue: #55752928

Change ConfigFileApplicationContextInitializer to add config file
property sources after existing sources. This allows environment
variables and system properties to override file properties.

Issue: #55739594

Remove '/resources/**' mapping since it can cause problems with the
'/**' when the developer defines their own 'resources' sub-folder.

Also remove default servlet config since the resources mapping renders
it redundant.

Issue: #55494446

Added logging to INFO SpringApplication to log when the application has
fully started and how long it took to load.

Create LiquibaseServiceLocatorInitializer to replace the standard
liquibase classpath scanning logic with SpringPackageScanClassResolver
which will work correctly in Spring Boot packaged executable JARs.

Issue: #55580628

Might need to revisit later.

The management endpoints were still all mixed up
with the user endpoints. Fixed that and extracted
user endpoints in to conditional block so not
protected if path explicitly set to empty string.

[#53029715]

Rework several aspects of database auto-configuration:

- Use RelaxedPropertyResolver to obtain property values
- Extract EmbeddedDatabaseConnection from EmbeddedDatabaseConfiguration
- Rename several configuration classes for consistency

Issue: #53028397

Update several existing auto-configuration classes to use the new
RelaxedPropertyResolver.

This commit also rename the spring.template property to spring.thymeleaf
in case we wish to support more templating engines in the future.

Create RelaxedPropertyResolver class that can be used to get values
from another PropertyResolver (probably an Environment) using the
same relaxed rules as the RelaxedDataBinder.

The commit extracts the relaxed naming rules from RelaxedDataBinder
into a new RelaxedNames class.

Issue: #55621278

Fix setTestOnReturn to use isTestOnReturn.

Management endpoints are still secure by default if
Spring Security is present, but now the default
user details have an ADMIN role, and a random password
(which is logged at INFO level if not overridden).

To override you add management.user.password (name, role)
to external properties.
