v3.0.0

Enhancements to make template-based index systems work better

• Added better config structure in test/config.js, splitting connection from index definitions
• elastic.create now takes optional options, which let it create indices with overrideable name and schema, useful for creating template-based indices
• elastic.putTemplate now takes a required index_patterns param, so patterns can be setup in environment config instead of hard coded (breaking)
• Updated docs
