fix: Adding configurable timezone support for log timestamps v2

[hrishikesh-nalawade]

Description

Currently, the API ML logs are generated with UTC timestamps. These changes will allow users to configure the timezone for log timestamps, giving them the option to set it to either their LOCAL or UTC. This configuration can be managed within the zowe.yaml file using the ZWE_zowe_logging_timezone variable.
