Summary:
Ref T11589. Previously, when we failed to load database configuration we just continued anyway, in order to get to setup checks so we could raise a better error.
There was a small chance that this could lead to pages running in a broken state, where ONLY that connection failed and everything else worked. This was accidentally fixed by narrowing the exceptions we continue on in D16489.
However, this "fix" meant that users no longer got helpful setup instructions. Instead:
- Keep throwing these exceptions: it's bad to continue if we've failed to connect to the database.
- However, catch them and turn them into setup errors.
- Share all the setup code so these errors and setup check errors work the same way.
Test Plan:
- Intentionally broke `mysql.host` and `mysql.pass`.
- Loaded pages.
- Got good setup errors.
- Hit normal setup errors too.
- Put everything back.
- Swapped into cluster mode.
- Intentionally broke cluster mode, saw failover to readonly.

Summary:
Hit this locally, with an error like:
> Version <empty string> is older than 1.9, the minimum supported version.
(Where `<empty string>` was just the empty string, not literally the text `<empty string>`.)
Be more careful about parsing versions, and parse the newer string.
Test Plan: Got "unknown version" with intentionally-broken test data, then clean readout.

Summary: Fixes T6011. See that task for discussion. We can detect when `memory_limit` will be the limiting factor for drag-and-drop uploads and warn administrators about it.
Test Plan: Fiddled configuration values and hit, then resolved, the issue.

Summary: Fixes T2605. Provide some instructions on configuring RDS properly. The "DB Parameter Group" thing in the web UI seems pretty easy to use, it's just not obvious that it's what you should be using.
Test Plan: Jiggled these warnings to trigger them, viewed the output, saw a table of values and a hint about RDS.

Test Plan:
Include existing setup issues in the ignore config option,
reduces the number of setup issues in the status bar, moves ignored
issues to the bottom of the list, and marks them as ignored.
Also include a string corresponding to no setup issue, and verify that
application does not break.

Summary:
This is basicaly a light version of D4286. The major problem with D4286 is that it's a huge leap and completely replaces the setup process in one step.
Instead, I want to do this:
- Add the post-setup warnings (yellow bar with "6 unresolved warnings...").
- Copy all setup checks into post-setup warnings (so every check has an old-style check and a new-style check).
- Run that for a little bit and make sure it's stable.
- Implement fatal post-setup checks (the red screen, vs the yellow bar).
- Run that for a little bit.
- Nuke setup mode and delete all the old checks.
This should give us a bunch of very gradual steps toward the brave new world of simpler setup.
Test Plan:
- Faked APC setup failures, saw warnings raise.
- Verified that this runs after restart (get + set).
- Verified that this costs us only one cache hit after first-run (get only).
