feat: capture message attributes for flow logs

[adesjardin]

Closes #78

Here's how it looks in studio

Validations:

Either "Attributes expression text" or "Message expression text" should be present while defining the flow-log-configuration
configuration xml:
<avio-logger:flow-log-configs> <avio-logger:flow-logs-config flowName="logger*" messageExpressionText="attributes.headers"/> </avio-logger:flow-log-configs>

Error handling

• When both the expression attributes are not defined, while building the application logger throws "IllegalStateException" with this exception message "One of attributesExpressionText or messageExpressionText must be defined in flow-logs-config"

- When `messageExressionText` is defined and resolved to an Object other than String type it will throw `ClassCastException` with message `Message expression text in flow-log-config needs to be a String`

How it Works

• When everything is configured correctly

`Message expression text` that is resolved as String will be appended to the default flow start logger `Attributes expression text` that is resolved as a Map will be appended to the log message as messageAttributes `com.avioconsulting.api.flow: {timestamp=2024-12-18T21:30:22.533Z, appName=logger-testFlow, appVersion=1.0.0, env=local, correlationId=499f0e51-bd87-11ef-a32d-4eb0274c4a15, message=Flow [logger-testFlow1] start Queue-stuff, messageAttributes={host=localhost:8082, cache-control=no-cache, user-agent=PostmanRuntime/7.29.0, postman-token=8cc87bf8-aa82-48c2-8561-11504d54730a, connection=keep-alive, accept=*/*, accept-encoding=gzip, deflate, br}, exception={statusCode=null, detail=null}, location={component=flow, rootContainer=logger-testFlow1, location=logger-testFlow1, fileName=logger-test.xml, lineInFile=45}}` `com.avioconsulting.api.flow: {timestamp=2024-12-18T21:30:22.538Z, appName=logger-testFlow, appVersion=1.0.0, env=local, correlationId=499f0e51-bd87-11ef-a32d-4eb0274c4a15, message=Flow [logger-testFlow1] end, messageAttributes={host=localhost:8082, cache-control=no-cache, user-agent=PostmanRuntime/7.29.0, postman-token=8cc87bf8-aa82-48c2-8561-11504d54730a, connection=keep-alive, accept=*/*, accept-encoding=gzip, deflate, br}, exception={statusCode=null, detail=null}, location={component=flow, rootContainer=logger-testFlow1, location=logger-testFlow1, fileName=logger-test.xml, lineInFile=45}}`

• flowName accepts wildCards either at the start or at the end example mq-listener* or *mq-listener or * for every Flow
