configure DefaultTTL for CloudFront

[tianleh]

Signed-off-by: Tianle Huang [email protected]

Description

As related issue states #1690, we observed that the latest build number is not updating even though the index.json file has changed content. After researching around, figure that the DefaultTTL shall be set to avoid the default behavior of caching for 1 day. Currently I set it to be 5mins to both get a recent build and also low the traffic impact to S3.

Issues Resolved

Resolves #1690

Tests

1. unit test
2. Deployed to my personal AWS account and verify the DefaultTTL change and also update the same file to see the change taking effect.

Current value of index.json https://d17qm4xnop70sv.cloudfront.net/ci/dbc/distribution-build-opensearch/2.0.0/index.json

updating the index.json to be 188.

confirm S3 has the new value.

Refreshing https://d17qm4xnop70sv.cloudfront.net/ci/dbc/distribution-build-opensearch/2.0.0/index.json and still get 166

waiting for 5min and will check again.

We can see that 188 is showing!
