Adds the following new properties:
- spring.application.pid
- spring.application.version
Refactors the ResourceBanner and the structured logging support to use
the new properties.
Closes gh-41604
Refine structured logging to support `Environment`, `ApplicationPid` and
`ElasticCommonSchemaService` injection. With these updates we are able
to remove the `ApplicationMetadata` class and simplify the parameters
passed to the layout/encoder classes.
Closes gh-41491
Update Logback and Log4j2 integrations to support structured logging.
Support for the ECS and Logstash JSON formats is provided out-of-the-box
and the `StructuredLogFormatter` interface may be used to if further
custom formats need to be supported.
Closes gh-5479
