nifi-toolkit-admin uses client.version of 1.2.0-SNAPSHOT

The nifi-toolkit pom declares client.version which is currently set to 1.2.0-SNAPSHOT, and then nifi-toolkit-admin has a dependency on nifi-client-dto using client.version.

The problem is that the release plugin will not automatically update client.version and then if you build with a clean Maven repo (or someone who never built master while at 1.2.0-SNAPSHOT) you get a failure:

nifi-toolkit-admin: Could not resolve dependencies for project org.apache.nifi:nifi-toolkit-admin:jar:1.2.0: The following artifacts could not be resolved: org.apache.nifi:nifi-client-dto:jar:1.2.0-SNAPSHOT, org.apache.nifi:nifi-web-security:jar:1.2.0-SNAPSHOT: Failure to find org.apache.nifi:nifi-client-dto:jar:1.2.0-SNAPSHOT
