RPM Support

(I am not sure if an issue already exists for this, there may be one but my search didn't find it)

As part of testing a patch related to errata applicability, we noticed there were lots of INFO-level messages from the yum profiler. For example, there were 1700 messages when applying a large set of errata:

# # the "grep -v 2015" is from laziness, to strip out some extra stuff I don't want

# less /var/log/messages | grep pulp | awk -F: '{print $4}' | grep -v 2015 | sort | uniq -c | sort -n | tail -n3
    329  celery.worker.job
    329  celery.worker.strategy
   1757  pulp.plugins.pulp_rpm.plugins.profilers.yum

The messages themselves are of the following form:

Can the log message be replaced with a smaller message, and/or have fewer messages printed? The messages themselves are helpful since the calculation can take some time and it's nice to know that Pulp is working on it, but the verbosity of the log makes it hard to see what it's doing exactly. A message somewhere in https://github.com/pulp/pulp_rpm/blob/master/plugins/pulp_rpm/plugins/profilers/yum.py#L94-L104 may be useful saying "expanded erratum to N rpms" but better solutions are welcome:)
