Major Description
The Samza webpage currently mentions SEPs (Samza enhancement proposals), which are on the wiki. I feel that the markdown/PDF JIRA attachment approach is a much better way to handle design documents.
I propose that we keep the SEPs stuff around, but link directly to the JIRAs/PDFs. We should also update the legacy SEPs to be .md/PDF attachments on the old JIRAs, and eliminate the SEP wiki section.
