COCOS-152 - Refactor algorithm execution and add visibility through logging and events (#176)

* * feat(agent): add support for binary algorithm execution
*
* feat(agent/algorithm): add Algorithm interface and binary implementation
*
* feat(agent/algorithm/binary): implement Run method for binary algorithm execution
*
* feat(agent/algorithm/logging): implement Stdout and Stderr writers for algorithm logging
*
* feat(agent/algorithm/logging_test): add tests for Stdout and Stderr writers
*
* feat(agent/events): add Service interface for sending events
*
* feat(agent/events/mocks): add mock implementation for Service interface
*
* refactor(agent/service): update runComputation method to use binary algorithm implementation

* * fix(logging.go): handle error when sending event in Write method of Stderr struct
* test(logging_test.go): add copyright header
* fix(backend_info.go): add missing type declaration in function signature
* fix(agent.go): rename progressbar variable to pb for clarity and consistency
