This is the first step of a multi-step SaaS engine extraction.
Looking ahead to an open source release, we need to make sure that
local authentication is treated as an "official" option, and not just
a hack I added for Kevin to do load testing outside our DC. So this PR
gets to green, and adds a CI step in "local authentication" mode.
This all probably feels a little hacky to you, Reader, but the goal of
this change is to ease the next step, which will be extracting the
37id and Queenbee integrations into a proprietary "SaaS mode" engine.
In service of that goal, this commit simply wraps all of the dependent
code and tests with a conditional check on
`config.x.local_authentication`.
