John Barker 531dcbf20a Add TAG_SETTING to list of allowed tags for the ec2 discovery plugin.
I am unable to set ec2 discovery tags because this setting was
accidentally omitted from the register settings list in
Ec2DiscoveryPlugin.java. I get this:

java.lang.IllegalArgumentException: unknown setting [discovery.ec2.tag.project]
