Description

Spinoff from SOLR-6677

Let's make it much easier to "turn on debug" by supporting a bin/solr start -V verbose option, and likewise a bin/solr start -q for quiet operation.

These would simply be convenience options for changing the RootLogger from level INFO to DEBUG or WARN respectively. This can be done programmatically in log4j at startup.

Could be we need to add some more package specific defaults in log4j.properties to get the right mix of logs
