Reduce STDERR logging to only WARNING and above.

Browse Source 
INFO logs are now only viewable in the log file, which is not written
by default. A new command line option --log-file can be used to control
where the log file is written.

INFO logs can be written to STDERR if --log-all-to-stderr is passed.

cquery is a low-latency C++ language server. Command line options:
--language-server
Run as a language server. This implements the language server
spec over STDIN and STDOUT.
--test-unit Run unit tests.
--test-index Run index tests.
--log-stdin-stdout-to-stderr
Print stdin and stdout messages to stderr. This is a aid for
developing new language clients, as it makes it easier to figure
out how the client is interacting with cquery.
--log-file <absoulte_path>
Emit diagnostic logging to the given path, which is taken
literally, ie, it will be relative to the current working
directory.
--log-all-to-stderr
Write all log messages to STDERR.
