Logging improvements

This patch was authored and released by @tanner0101.

Improves readability of framework log messages and adds API for controlling error logging (#2412).

• Downgraded several instances of .error level logging to .debug.

Note: The developer should have control over all .error level logs generated as the result of incoming HTTP requests.

• Added logLevel property to DebuggableError.

Note: This allows DebuggableError's to control how they are reported to logs. Vapor's default "route not found" error uses this new API to log at .debug level.

• Fixed an issue causing stack traces to be included when logLevel > .trace.

Note: Stack traces were only meant to be reported at the .trace level as they generate significant output.

• Error source information is no longer duplicated in logs.
