Solr 7121: : Solr nodes should go down based on configurable thresholds
Code:
SolrConfig - Adds a new config-node CoreDownThresholds (Example config in
data_driven_schema_configs/conf/solrconfig.xml)
SolrCore - Based on coreNameExpression in the above config, each core gets
its own config for thresholds.
SolrHealthMonitor* - Main logic for monitoring health of each core. Brings
down a core if its stats look bad and brings the same up if the stats improve.
ResponseTimeMonitor - Helper to SolrHealthMonitor, focussed solely on
monitoring response-time of queries.
Tests:
CoreDownOnBadSelectStatsTest
CoreDownOnHighLoadTest
CoreDownOnLongRunningQueriesTest

SOLR-7121: Solr nodes should go down based on configurable thresholds and
not rely on resource exhaustion
Code:
SolrConfig - Adds a new config-node CoreDownThresholds (Example config in
data_driven_schema_configs/conf/solrconfig.xml)
SolrCore - Based on coreNameExpression in the above config, each core gets
its own config for thresholds.
SolrHealthMonitor - Main class for monitoring health of each core. Brings
down a core if its stats look bad and brings the same up if the stats improve.
ResponseTimeMonitor - Helper to SolrHealthMonitor, focussed solely on
monitoring response-time of queries.

Refactor SolrHealthMonitor
SolrHealthMonitor is broken into:
1) SolrHealthMonitor - Interface holding public APIs
2) SolrHealthMonitorBase - Abstract class with logic to bring cores up and
down
3) SolrHealthMonitorImpl - Has logic to get real stats like thread-count,
gc-time, long-queries etc.
