--------------------------------------------------------------
New patch with a couple of additions:
1) Added code during initialization of the collectorFactories to handle
condition where default collectorFactory is not defined in solrconfig.xml. This
makes this patch backwords compatible with 4.* solrconfigs.
Tests now run without null pointers.
2) Added the CollectorSpec class to hold the collector http parameters. This
class will implement hashCode and equals and will be added to QueryResultKey.
The QueryResultKey implementation of this is not in this patch so more work
still needs be done on getting this cache ready.
This patch has been tested with the default collector factory with sorting and
ranking queries and in distributed mode.

> This issue is to add configurable custom collectors to Solr. This expands the
> design and work done in issue SOLR-1680 to include:
> 1) CollectorFactory configuration in solconfig.xml
> 2) Http parameters to allow clients to dynamically select a CollectorFactory
> and construct a custom Collector.
> 3) Make aspects of QueryComponent pluggable so that the output from
> distributed search can conform with custom collectors at the shard level.
