[nikhil-sk]

Issue #, if available:

Description of changes:

1. TS has upgraded from using log4j1.2 to log4j2, as part of 0.5.1 release.
2. The pytorch inference toolkit supplies the properties file to be used for logging config, to torchserve, and needs to be upgraded.

LOGS

Confirmed by building a DLC that consumes this package (specifically a package built out of this PR):

it has the following expected output on loading a model:

Sagemaker TS environment variables have been set and will be used for single model endpoint.
