Add get function in ssh.py

JIRA: YARDSTICK-904

This task is about to implement a get function in ssh.py to
fetch desired files/folder in a remote VM to a local path.

In some test cases, test tools will produce results in files.
We want retain the original result files and archive them in
Yardstick docker for future usage.
