Revert "Merge pull request #2428 from johnmccutchan/embedder_yaml"

This reverts commit 93b11edc8225e1c97bd8b1b40ba8e5665fcc9bc6, reversing
changes made to cb4107191db3d83021e1fa47bade7bf6bcae09d8.

This was requested by @johnmccutchan because this change broke the
analyzer, which only uses SDK version 1.14.1, since that's what we pull
in. He said he'd try again on Monday.
