Allow solr cli run tool to use quiet or verbose log levels

Trivial fix

According to the solr control script reference (

https://lucene.apache.org/solr/guide/8_3/solr-control-script-reference.html#solr-control-script-reference)

, passing -v changes the logging level of log4j from INFO to DEBUG. This isn’t the case when used with any of the examples passing -e. I frequently use a command like

bin/solr start -e cloud -noprompt

to spin up a quick 2 node cluster and would’ve expected -v to enable debug.

This is a trivial patch to allow the examples to run with DEBUG (likewise WARN for -q): 
bin/solr start -e cloud -noprompt -v
