Create debugging script/tool for difficult to debug Azure Batch scenarios

[MattMcL4475]

Problem:
There is a scenario whereby no logs are available for a task and there is seemingly no information available to debug what happened in Batch.

Solution:

• Write a script/binary that will reach out to a pool's nodes, connect to them, and start streaming their batch agent logs to a storage account. This can be a script/binary added to the repo as a debugging tool. It should be very specific in its scope and no need to spend many cycles making it generalizable or extensible at this point.
• Add to the Wiki clear instructions for when and how to use it, and what to do with the results.
