NOISSUE - Introduce NATS Jetstream as Default ES (#1907)
* Refactor message broker implementation

This commit refactors the Nats message broker implementation to include pubsub options. These changes include:

- Adding `Option` func that takes in the URL and prefix
- Implement `WithStream` option which can create a different stream for nats stream
- Implement `WithExchange` option which can create a different exchaange for rabbitmq channel
- Implement `WithPrefix` option which allows to you change the publisher prefix

These changes improve the organization and readability of the codebase.

* Fix adds options to messaging `PubSub` interface

Adding options to PubSub interface allows the use of messaging
package to do es.

The changes in this commit ensure that the code handles errors
properly and provides more informative error messages when
encountering unexpected types.

* Add NATS event publisher implementation

This commit adds the implementation of the NATS event publisher.

The NATS event publisher is responsible for publishing events
to a NATS messaging system. It uses the `messaging`
package to interact with the messaging system.

The implementation includes the following features:

- Publishing events to NATS using the `Publish` method.
- Marshaling events to JSON before publishing.
- Setting the message subject and headers based on the event.
- Handling errors during publishing.

This implementation is built with the `!rabbitmq` build tag,
which means it will only be compiled if the `rabbitmq` build tag
is not present.

The NATS event publisher is part of the Mainflux events package
and provides support for the Mainflux NATS events source service functionality.

* Add configurable implementation for events store

This commit adds a new file `brokers_*.go` which contains the implementation for the different event store. The file includes functions for creating a new publisher and subscriber using different es store.

This commit also includes an `init` function that logs a message indicating that the binary was built using the respective package as the events store.

The purpose of this commit is to add support for alternative events store.

* Refactor Makefile and Semaphore configuration

The Makefile has been refactored to include the `MF_ES_STORE_TYPE` tag in the `go build` command. Additionally, the Semaphore configuration has been updated to include a new task for compiling with Redis as the broker type.

This commit addresses the need to compile the codebase with Redis as the event store type and includes the necessary changes in the Makefile and Semaphore configuration.

* feat(docker): update environment variables for message broker

The commit updates the environment variable `MF_ES_STORE_TYPE` in the `docker/.env` file. The variable is changed from `${MF_MQTT_BROKER_TYPE}` to `${MF_MESSAGE_BROKER_TYPE}` to accurately reflect the type of message broker being used. This change ensures that the correct message broker is configured for the Event Store.
