Add LoggerFactory for structured logging

[o-eissa]

Fix #10

This PR introduces a new LoggerFactory class in factories.py. This class provides a method get_logger to create a logger with a custom format and behavior to output structured logs following the format in the Go sdk PR
Key features of the LoggerFactory class include:

• The get_logger method, which creates a new logger with the specified name and log level. The log level defaults to logging.DEBUG if not provided and name to the default name logger.
• A custom formatter LowerCaseLevelNameFormatter is used to convert the log level name to lowercase.
• The log format includes the timestamp, log level, message, hostname, application name (filename), and line number.
• The hostname is automatically populated using socket.gethostname().

Example:
{"timestamp":"2024-01-21T09:37:47Z","log-level": "debug","message":"sdk disposed","hostname":"DESKTOP-0QCUII1", "application":"default.py", "line-number":"default.py:63"}
