Caffe integration test fails because it is not able to download files from caffe server

Description

Caffe integration test fails because it is not able to download files from caffe server.

Failed build:
https://builds.apache.org/blue/organizations/jenkins/incubator-mxnet/detail/v0.12.0/4/pipeline

• If license permits, we should be hosting these files in S3 and downloading from there for the purposes of tests instead of depending on external servers.
• The test can also check if the file already exists in the file system to avoid downloading again and again every time.

Environment info (Required)

CI builds.

Steps to reproduce

Build and run integration test.

Reviewed the license, and it doesn't pose any restriction on use. I will move its hosting to s3 and re-enable.
