[SOLR-15805] SolrCloud node can be zombie with some startup exceptions

• Type: Bug

Description

In SolrDispatchFilter.init() (all Solr versions), when CoreContainer is created (call to createCoreContainer()), if an exception is thrown that is not an Error (for example, a SolrException), the issue is logged "Could not start Solr. Check solr/home property and the logs" but the init() method does not fail and the node is left in a non functional state until it is killed by some external mechanism.

I suggest to change this here and treat all exceptions the way we treat errors and throw from SolrDispatchFilter.init().
