Developer Curb Appeal: doc: Explaining Production vs. Dev environment, Java Memory, etc.

Issues:

Which things are OK for prod, which are not. For example, if we ever do "schemaless", why it might not be good in prod.

Locking down REST API access

Sizing, RAM, disk (and type of disk)

JVM memory advice, Xms, Xmx, physical memory, Java 6 vs. Java 7

Where to turn logging on and off

How much to obsess about schema.xml settings

Memory hot spots: sorting, facets, etc

Using external vs. embedded ZooKeeper

Well known addresses and syntax for ZK nodes

Caching, etc.
