In Solr 6.3 (SOLR-6677) we reduced a lot of noisy logging in the default
start/stop scenario. We ended up with a very compact set of log lines. I just
realized that this is getting fatter for every release, and now a solr start -f
looks like this on my laptop:
$ solr start -f
*** [WARN] *** Your open file limit is currently 256.
It should be set to 65000 to avoid operational disruption.
If you no longer wish to see this warning, set SOLR_ULIMIT_CHECKS to false in
your profile or solr.in.sh
*** [WARN] *** Your Max Processes Limit is currently 1418.
It should be set to 65000 to avoid operational disruption.
If you no longer wish to see this warning, set SOLR_ULIMIT_CHECKS to false in
your profile or solr.in.sh

Am I alone valuing a much more minimalistic output and hiding stuff that won't
add value? After pruning away what I see no value in, here's what I end up with:

That's from 31 to 12 lines. I don't want to see file limit warnings on a dev
laptop, and Jetty's lack of JSP support is totally irrelevant :)
The line "SSLCredentialProviderFactory Processing SSL Credential Provider
chain: env;sysprop" is also popping up even in non-SSL and for things like
bin/solr status. Why?
If you all agree I'll open a JIRA and solve some of this with INFO->DEBUG
changes, and others in log4j2.xml (e.g. o.e.j.s.session -> WARN)
