Removed the `ramsey\uuid` dependency

• Removed the ramsey\uuid dependency.
  • If the lib is present, it will still use the libs implementation. But to make the library dependency free it was made optional. It will internally still generate a UUID.
• The lib requires now PHP ^8.1, unmaintained version will no longer be supported.

Enabled PHP8

• Enabled PHP 8 in composer.json
• Updated CI configs
• Added an interface for the CorrelationID

Feature release: Added a pass-through option

In the case you need to pass an existing CID from another service to the current microservice you might want to keep the ID based on the received header value.
