Sammy Kerata Oina 64f7e7f7fd NOISSUE - Refactor single algorithm processing (#117)
* Refactor single algorithm processing

Simplified the agent service's algorithm handling logic to process a single algorithm instead of multiple. This change:
- Removed the `Algorithms` type and associated stringer implementation.
- Updated the state machine and service logic to expect a singular algorithm, aligning the agent's internal state transitions with the new model.
- Adjusted the manager service and computations test server to mirror these changes in their respective payload structures, ensuring API and test consistency.
- Altered README files to reflect the simplified interaction model and removed outdated descriptions.
- Reverted the protoc-gen-go version used for generating protobuf files to maintain compatibility with the rest of the codebase.

The single-algorithm approach streamlines the computation running process, reducing complexity and potential error conditions. It directly impacts how external services will construct and send computation requests.

Sammy Kerata Oina 2e612a2867 COCOS-108 - Enhanced state machine Synchronization (#112)
* Enhanced state machine synchronization

Introduced a wait group to the state machine to manage go-routine synchronization effectively. The Start method now ensures that the state machine's execution is tracked, preventing potential early termination of go-routines during state transitions. The test suite is updated to wait for the go-routine to complete before proceeding, ensuring more reliable test execution.

Sammy Kerata Oina 4ea9ff6531 NOISSUE - Add message broker on agent and manager (#17)
* Fix bug in agent state machine

The bug in the agent state machine caused an error when attempting an invalid transition. This commit fixes the bug by properly locking and unlocking the state machine before and after transitioning to the next state. Additionally, the logger now correctly logs the current and next state during a valid transition.

Signed-off-by: SammyOina <sammyoina@gmail.com>

* Fix race condition in state machine

The commit fixes a race condition in the state machine implementation in the `Start` method. The race condition occurs when multiple goroutines try to access and modify the state concurrently. To fix this, a mutex lock and unlock are added around the critical sections of code to ensure exclusive access to the state variable. This prevents race conditions and ensures the state transitions are executed correctly.

* Fix race condition in StateMachine.Start()

The StateMachine.Start() method was experiencing a race condition
when multiple events were being processed concurrently. This was

by adding proper locking and unlocking around the state update
operation. Additionally, the logging statement has been updated
to include the previous and next states for better debugging.

* Fix Makefile to properly set DOCKER_PROJECT and COCOS_MESSAGE_BROKER_TYPE

The Makefile has been updated to fix an issue with setting the DOCKER_PROJECT and COCOS_MESSAGE_BROKER_TYPE variables. The USER_REPO variable is now used to generate the DOCKER_PROJECT name following the Docker Compose guidelines. Additionally, the COCOS_MESSAGE_BROKER_TYPE variable is now properly set to "nats" if it is empty. This ensures that the correct values are used when compiling and installing the service.

Summary:
Fix Makefile to properly set DOCKER_PROJECT and COCOS_MESSAGE_BROKER_TYPE

Details:
- Update USER_REPO variable to generate DOCKER_PROJECT name
- Set COCOS_MESSAGE_BROKER_TYPE to "nats" if empty

* Fix Makefile Docker profile assignment and build flags

The Makefile was updated to fix the assignment of the Docker profile and build flags. The Docker profile is now assigned based on the value of COCOS_MESSAGE_BROKER_TYPE, and if it is not provided, the default value is set to "nats". The build flags were also updated to include the COCOS_MESSAGE_BROKER_TYPE value as a tag for the Go build process.

This commit addresses the issue with the Docker profile assignment and ensures that the correct build flags are used during the build process.

Additionally, the NATS ports in the Docker environment variables were incorrect. The COCOS_NATS_PORT and COCOS_NATS_HTTP_PORT have been updated to the correct values.

These changes ensure that the agent service uses the correct notification topic and the NATS ports are properly configured.

- In agent/service.go:
  - Added a goroutine to start the StateMachine
  - Sent the start event to the StateMachine

- In agent/state.go:

* Fix race condition in agent service initialization

The commit fixes a race condition in the agent service initialization.
Previously, the `New` function in `agent/service.go` would start the state machine
goroutine before initializing the `sm` field. This could lead to a race condition
where the state machine would access uninitialized fields.

To fix this, the `New` function now takes a `context.Context` argument and passes it
to the `Start` method of the state machine. Additionally, a `sync.Mutex` has been
added to the `StateMachine` struct to ensure thread safety.

This commit addresses the race condition and ensures proper initialization of the agent service.

* Fix bug in agent service and state

The commit fixes a bug in the agent service and state files.
Previously, the condition to check the state in the agent service
was incorrect. It was checking the state directly instead of
using the GetState() method. This has been fixed by using the
GetState() method to check the state.

Additionally, a new GetState() method has been added to the
StateMachine struct in the state file. This method retrieves
the current state by acquiring a lock and returning the state
value.

The changes have been tested and verified to resolve the bug
and improve the accuracy of state checking in the agent service.
