pkgstore files should have file type of text/plain

[rufuspollock]

Copying from openknowledge-archive/dpr-api#273

When we upload any file in pkg store the file type by default set to binary/octet-stream. But we want text/plain:

e.g. datapackage.json has binary/octet-stream should be json. Try:

curl -I http://pkgstore-testing.datahub.io/core/finance-vix/latest/datapackage.json

Why is this a problem:

• when you click on Metadata in the views page the datapackage.json downloads rather than being viewable in the browser.
• if you view these files you get auto-download. Like github raw your want text/plain (this is also good for security)

Want right content type for JSON and for everything else set text/plain (or could even just have text/plain for json too).

Solution

Add Content-Type while publishing data to S3

Acceptance Criteria:

• In pkgstore all data should be of type text/plain

This is at least in part an issue upstream in https://github.com/frictionlessdata/datapackage-pipelines-aws - we need to be able to set file type.

FIXED. Fixed upstream and then used here when via bump of dependency to v0.0.8 in c41c533#diff-2eeaed663bd0d25b7e608891384b7298
