* Fix return nil
A nil error is an interface having nil value but a non-nil type.
This leads to unexpected errors in the code well-documented here:
https://golang.org/doc/faq#nil_error
We fix this by passing an additional parameter to handle it.

* Bring back auto-generated line
Adds Advanced Logging to server. Advanced Logging is an optional logging capability that allows customers to send log records to any number of destinations.
Supported destinations:
- file
- syslog (with out without TLS)
- raw TCP socket (with out without TLS)
Allows developers to specify discrete log levels as well as the standard trace, debug, info, ... panic. Existing code and logging API usage is unchanged.
Log records are emitted asynchronously to reduce latency to the caller. Supports hot-reloading of logger config, including adding removing targets.
Advanced Logging is configured within config.json via "LogSettings.AdvancedLoggingConfig" which can contain a filespec to another config file, a database DSN, or JSON.

* MM-14145: The config store Set will now Save automatically
When UpdateConfig (and configStore.Set) is called in admin.go and
config.go, commonStore.Set now takes a store-specific persist function.
It uses that persist function to save the configuration automatically.
Removed: Now callers do not have to call configStore.Save or
app.PersistConfig, and those functions have been removed.
Possible downside: this means a "failed to persist config" error can now
be thrown during a app.UpdateConfig or commonStore.Set call. But
considering application code never really sets a config without saving
it (except in the test cases, which were testing that -- see below), it
seems fine to group these responsibilities.
Also removed: tests for 'set without save'. Since that can not happen
anymore, the tests are not needed.
* Removed Save completely, cleaned up formatting, joined save test with
set tests.

Introduce an interface and concrete implementation for accessing the config.
This mostly maps 1:1 with the exiting usage in `App`, except for internalizing the watcher. A future change will likely eliminate `App.PersistConfig()` and make this implicit on `Set` or `Patch`
* experimental file test changes
* emoji: move file driver checks from api4 to app
It is no longer possible to app.UpdateConfig and provide an invalid configuration, making it hard to test this case. This check doesn't really belong in the api anyway, since it's a configuration validity check and not a permissions check. Either way, the check now occurs at the App level.
