Move logs and static files from /tmp to /var

[davidsmejia]

Context

Currently, when we launch the API we write Nginx access and error logs to /tmp as well as serving generated static files. This seem to be an issue after deploy. Trying to tail logs from /tmp/access.log does nothing which indicates that the container cannot write to that file. Similarly, static files are unable to be served from /tmp.

Problem or idea

We should move nginx logs and static content to their appropriate location in /var.
Nginx logs should be located at /var/log/nginx/access.log and /var/log/nginx/error.log
Static content should be served in nginx from /var/www/volumes_static

Solution or next step

• update nginx.conf to write logs to `/var/log/nginx``
• update nginx.conf to serve static files from /var/www/volumes_static
• update user data script template to rotate logs from /var/log/nginx
• update user data script to map static directory to /var/www/volumes_static
