Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost

	# Ver 2.1, By Reza Hashemi
	# Automate EC2 instance setup and Install latest Ansible and its dependencies via pip (recommended method)
	# The cloud init script detects the EC2 instance platform at launch and uses preferred package manager
	# AWS cloud init script to install ansible on startup, autodetects required package manager
	# Add as user data inside advanced details at AWS EC2 configure instance details (step 3)
	# Changes:
	# Ver 2.1 Tested on Centos 6
	# No issues with pynacl and cryptography
	# Ver 2 Tested on RHEL, Centos 7, Ubuntu, SUSE, Fedora 23-25, Debian
