re:dash client over Redshift

Access it here.

To deploy, launch an EC2 instance from AMI `redash-20151001`.  Once launched add the instance to the Redshift security group and the redash load balancer.

To manage users, `ssh` to the host, `cd /opt/redash/current`, and then `sudo -u redash bin/run ./manage.py users`.

Here are steps to create the AMI:

1. Base AMI: Ubuntu 14.04 LTS HVM 64-bit
   1. The user is "ubuntu"
   2. Remember to open HTTP 80 for testing
2. Connect to the instance
   1. `sudo apt-get update`
   2. `sudo apt-get -y -q dist-upgrade`
   3. `sudo apt-get -y -q autoremove` 
   4. `sudo apt-get -y -q autoclean`
   5. Run the bootstrap script
   6. Test that the website is up and running
3. Edit `/opt/redash/.env` and change the cookie secret
4. Go to `/opt/redash/current` and change the admin password `sudo -u redash bin/run ./manage.py users password admin <new password>`
5. Set up Google OAuth in `/opt/redash/.env`.  The credentials are also backed up in belltown
6. Restart redash `sudo supervisorctl restart redash_server`
7. Set up a load balancer behind Route53.  Make sure the health check is on `/login` which the redash server returns 200
8. Connect to Redshift. Note Redshift is in a different AWS account in on VPC.  Must add the instance's IP to the Redshift's security group.  Test the connection using `telnet`
9. Configure the data source for Redshift by logging in as `admin` and browsing to `/data_source`
