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

  Prevent test failures under Windows
  Fixed handling of spaces in file paths

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.

# By Adrian Pillinger
* pull37:
  Fixing typo in the documentation that incorrectly named a property.

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.

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

  Added Joda-time managed dependency

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.

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.

[Finishes #55621314]

Rework several aspects of database auto-configuration:

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