[TimeSeries]: Reduced image size and removed oneAPI tool kit (open-edge-platform#845)

focuses on reducing the Docker image size and removing the oneAPI toolkit while updating the Time Series Analytics microservice. The changes include significant code refactoring to improve logging practices, updating Python dependencies, and modifying the Docker build process for optimization.

Standardized logging format throughout the codebase to use parameterized logging instead of f-strings
Updated Python dependencies and removed oneAPI toolkit from Docker configuration
Refactored code structure and improved documentation with proper docstrings
