for these signals to be useful yet.
This reverts commit 2c8c2cfa14.
closes#452
* stack-based execution model, documented in documentation
* circbuf for capturing hook output
* built-in hooks for postgres and mysql
* refactor docs, too much info on the jobs page, too difficult
to discover snapshotting & hooks
