[FEATURE] Add support for sending additional metadata in the `MessagingInterface`

[lsampras]

Feature Description

In the current implementation of message interface I can only send a Message & a timestamp associated with the message, There is no accomodation to send additional metadata about the message which isn't part of the data but could be propogated to the downstream implementations,

These could be used downstream as kafka headers or redis hashes or partition keys.

Possible Implementation

metadata can be a simplistic HashMap<String, String> and can be either accomodated as a new param in the MessagingInterface or a new method on the Message Interface.

The implementers of MessageInterface can handle it as follows

1. Kafka Send the metadata as headers
2. EventLogger Log the metadata as a separate key along with the raw data

whenever I am running the docker-compose up -d all the services are working but the hyperswitch-hyperswitch-server-1 is exiting everytime starting the container, how can I fix this

[lsampras]

Hey @tanbirali , Can you share the logs that are emitted on docker failure ? you can get them via docker compose logs hyperswitch-server..

Also these are the steps for running hyperswitch locally via docker compose you can walk through them again if anything is amiss...

There were some similar issues reported and solved in the discord can check if your issue is present there
