use cases for name and type properties for datastores can be confusing

Customers are asked to define a nexus-store.properties file with contents similar to this:

username=<postgres_user>
password=<postgres_password>
name=nexus
type=jdbc
jdbcUrl=jdbc\:postgresql\://localhost\:5432/nxrm

Problem

There is no explanation about what the "name" and "type" names are for.

Expected

1. Document what the properties are for and/or if properties should have default values that a user should not modify, then don't ask the user to define these properties, instead set the defaults internally. - Done
2. If properties should have default values that a user should not modify, then don't ask the user to define these properties, instead set the defaults internally.
