Prefer eyre::WrapErr instead of Context and eyre::OptionExt instead of ContextCompat

Moves from an async worker (bad abstraction) to a connection pool.
bb8does not have an obvious way to kill connections involved in a panic, so as a (hopefully temporary) workaround, a wrapper is used that checks for panics on drop and, if so, replaces the connection with aNonebefore it is returned to the pool, at which point it is identified as dead viahas_broken.Draft asit compiles but is not yet tested.
