Major Description
After some discussions on the solr-user list, it appears there is a need for the ability to promote a specific core/instance to be the leader of a shard.
As I understand it, currently any master election is random, and the leader is chosen by chance.
Workarounds are removing/adding cores until the right server is elected, but this not ideal/efficient.
PS: Thank you SOLR developers for your contributions!
