Summary: Add a default cluster policy
Key: SOLR-12845

Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Shalin Shekhar Mangar
[~varunthacker] commented on SOLR-12739:
bq. We should also ship with some default policies - "Don't allow more than one
replica of a shard on the same JVM" , "Distribute cores across the cluster
evenly" , "Distribute replicas per collection across the nodes"
This issue is about adding these defaults. I propose the following as default
cluster policy:
{code}
# Each collections replicas should be equally distributed amongst nodes
{"replica": "#EQUAL", "node": "#ANY"}
# All cores should be equally distributed amongst nodes
{"cores": "#EQUAL", "node": "#ANY"}
# Each shard cannot have more than one replica on the same node if possible
{"replica": "<2", "shard": "#EACH", "node": "#ANY", "strict":false}
{code}
