Quiet down Yum's logging. Fixes #3855.

Salt does not need any of `sys.stdout`, `sys.stderr` and `syslog` logging handlers which are configured by Yum, specially because we're using Yum as an API, not as another CLI tool. Any logging will go through salt's logging handlers.
Just set the levels as the Yum package does.
Make sure that an iterable is available. Fixes #8556.
Document that Raven is a required dependency. Fixes #8557.
Strip ALL non windows scripts from `sdist`.
Invert debugging logic.
Gracefully handle certain bad yaml conf files.

Parsing a conf file as valid yaml might still yield something other than
a dictionary, which is required. So check for that case, log an error,
and continue the same way that an invalid yaml conf file would be handled.
