Trimming Getting Started content to make it more of a brief intro to custom 
properties. Admin Guide will contain info about creation and configuration. 
NIFI-2556 will cover info needed from a user's perspective.

Getting Started:

Custom Properties within Expression Language

In addition to using FlowFile attributes, you can also define custom properties 
for Expression Language use.  Defining custom properties gives you additional 
flexibility in processing and configuring dataflows.  For example, you can 
refer to custom properties for connection, server, and service properties.  
Once you have created custom properties, you can identify their location in the 
nifi.variable.registry.properties field in the nifi.properties file. After you 
have updated the nifi.properties file and restarted NiFi, you are able to use 
custom properties as needed.


Admin Guide:

Custom Properties

To configure custom properties for use with NiFi’s Expression Language:

-Create the custom property. Ensure that: 
 --Each custom property contains a distinct property value, so that it is not 
overridden by existing environment properties, system properties, or FlowFile 
attributes.
 --Each node in a clustered environment is configured with the same custom 
properties.
-Update the nifi.properties file with the location of the custom property files.

Property  Description
nifi.variable.registry.propertiesThis is a comma-separated list of 
location paths for one or more custom property files.

First draft of content to add to Getting Started guide after “Working with 
Attributes” section:

Custom Properties within Expression Language

In addition to using FlowFile attributes, you can also define custom properties 
for Expression Language use.  Defining custom properties gives you additional 
flexibility in processing and configuring dataflows.  For example, you can 
refer to custom properties for connection, server, and service properties.

When you define custom properties, ensure that the following criteria are met:

-Each custom property contains a distinct property value, so that it is not 
overridden by existing environment properties, system properties, or FlowFile 
attributes.
-Each node in a clustered environment is configured with the same custom 
properties. 

Once you have created custom properties, you can identify their location in the 
nifi.variable.registry.properties field in the nifi.properties file. After you 
have updated the nifi.properties file and restarted NiFi, you are able to use 
custom properties as needed.
