* Replace Nats with Nats Jestream For PubSub Signed-off-by: rodneyosodo <blackd0t@protonmail.com> * Add Stream Description Signed-off-by: rodneyosodo <blackd0t@protonmail.com> * Subscribe using wildcard Signed-off-by: rodneyosodo <blackd0t@protonmail.com> * Add consumers description Signed-off-by: rodneyosodo <blackd0t@protonmail.com> * Remove unused queue variable Signed-off-by: rodneyosodo <blackd0t@protonmail.com> * Add extra configs to stream Signed-off-by: Rodney Osodo <socials@rodneyosodo.com> * Use inline error handling Signed-off-by: Rodney Osodo <socials@rodneyosodo.com> * Fix connection leak in NATS publisher The publisher struct in pkg/messaging/nats/publisher.go was modified to include a new `conn` field of type `*broker.Conn`. This change was made to fix a connection leak issue in the NATS publisher. The `NewPublisher` function was updated to assign the `conn` parameter to the new `conn` field in the publisher struct. Additionally, the `Close` method in the publisher struct was modified to close the `conn` connection. This commit fixes the connection leak issue in the NATS publisher and ensures that connections are properly closed.

To support this functionality, the `strings` package has been imported in the `pubsub.go` file to check the topic. Signed-off-by: Rodney Osodo <28790446+rodneyosodo@users.noreply.github.com> * feat : remove internal logic to keep subscribers Signed-off-by: Rodney Osodo <28790446+rodneyosodo@users.noreply.github.com> * feat(messaging): add function to format consumer name This commit adds a new function to the `pubsub` package in the `messaging` module. The function is called `formatConsumerName` and is used to generate a consumer name for NATS messaging. The function takes two parameters, `topic` and `id`, and returns a formatted consumer name. The consumer name is generated by concatenating the `topic` and `id` parameters, with some restrictions on the characters that can be used. This function will be useful for creating durable subscriptions in NATS messaging.

Messaging
messaging package defines Publisher, Subscriber and an aggregate Pubsub interface.
Subscriber interface defines methods used to subscribe to a message broker such as MQTT or NATS or RabbitMQ.
Publisher interface defines methods used to publish messages to a message broker such as MQTT or NATS or RabbitMQ.
Pubsub interface is composed of Publisher and Subscriber interface and can be used to send messages to as well as to receive messages from a message broker.
