Improve on extensibility of BuiltConfiguration/DefaultConfigurationBuilder

ConfigurationBuilder interface:

• added convenience methods to ConfigurationBuilder interface (to better sync with existing methods)
• annotated as @ProviderType (see ticket)

DefaultConfigurationBuilder

• removed fields for configuration attributtes - they are set as atttributes directly on rootComponent instead
• added a protected generic support method 'getOrCreateComponent' (also for subclasses to use)
• added methods:
  • public ConfigurationBuilder<T> addProperty(PropertyComponentBuilder)
  • protected Optional<String> getRootProperty(String)
  • protected Optional<Component> getComponent(String)
  • protected Component getOrCreateComponent(String)
  • protected Component getRootComponent()
  • added setMonitorInterval(int) and setShutdownTimeout(long) for direct setting
  • added setMonitorInterval(int, TimeUnit) and setShutdownTimeout(String, TimeUnit) so both methods have a string and a number variant
  • added protected getters for attributes and child components
• moved initialization from "build(boolean)" to BuiltConfiguration constructor since everything is transported overr the rootComponent now
• added more argument validation
• improved javadoc

BuiltConfiguration:

• removed Component fields (appenders/loggers/etc.) and replaced with protected generic Optional accessors directly from 'rootComponent'
• attribute processing done in constructor (moved from DefaultConfigurationBuilder#build())
• added protected accessors (getRootComponent, getChildComponent, and getChildComponents) so subclasses can access the root component
• guarded int/long conversion for 'monitorInterval' and 'shutdownTimeout'
• added more argument validation
• improved javadoc

• added CustomBuiltConfigurationTest unit-tests
• updated "revision" in main pom.xml to 2.25.0 due to baseline majorr change to ConfigurationBuilder interface
• updated package-info.java versions to 2.25.0 in
  • org.apache.logging.log4j.core.config.builder.api
  • org.apache.logging.log4j.core.config.builder.impl
  • org.apache.logging.log4j.core.config.properties
• fixed bug in UnitTest Configurator1Test where the test configuration was being inittialized twice

NOTE to reviewers - please review carefully due to API changes and specifically:

• the move of all attributes/components directly onto rootComponent in DefaultConfigurationBuilder
• the move of initializatiton logic for attributes from DefaultConfigurationBuilder#build to the BuiltConfiguration constructor

@ppkarwasz - build failed - but I don't think I can fix it?
