Add ssh function
Add ssh function

The branch "no-bash" was created to figure out a way to establish an
SSH tunnel using Python since Condor submit jobs require a single
executable meaning that a Bash script which establishes an SSH tunnel
and then calls a Python script wouldn't work. To ease development,
I started by just trying to establish a SSH tunnel (ssh.py). This
commit adds the ssh function was worked out in ssh.py into
write_to_gsheets_AGG.py.
