Fix/update dependencies to fix vulnerability

[aokumasan]

Summary

• Upgrade botocore and awscli versions to fix below vulnerability.
  • urllib3
  • Jinja2
• pyyaml is not upgraded in this p-r, because awscli depends on pyyaml 3.x (please see https://github.com/aws/aws-cli/blob/1.16.144/setup.py#L31)
• jessie-updates apt repository was expired, so upgraded docker image version.
• Delete Pipfile.lock to support multiple python version for development.

Review

• docker-compose build
• vim .env
