* SOLR-7547: Short circuit SolrDisptachFilter for static content request. Right now it creates
a new HttpSolrCall object and tries to process it. (Anshum Gupta)
* SOLR-7333: Make the poll queue time a leader uses when distributing updates to replicas
configurable and use knowledge that a batch is being processed to poll efficiently.
