gatsby-source-filesystem gives depreciation warning on nodejs 12

[erik-am]

Description

Calling createRemoteFileNode() in gatsby-source-filesystem results in the following depreciation warning on node 12.

(node:94963) [DEP0066] DeprecationWarning: OutgoingMessage.prototype._headers is deprecated

I tried the latest version of gatsby-source-filesystem.

The warning is written to STDERR which makes our build pipeline fail.

Steps to reproduce

1. Make a plugin that calls createRemoteFileNode() to download a remote file for certain nodes.
2. Add a page that requires the node so that the plugin is triggered.
3. Run gatsby develop or gatsby build to get the depreciation warning.

Expected result

No depreciation warning.

Actual result

We get a depreciation warning, which makes our build pipeline fail:

(node:94963) [DEP0066] DeprecationWarning: OutgoingMessage.prototype._headers is deprecated
