Saw the following traceback when trying to use the s3 publisher:

<pre>
s3("tmp") {
entry('...', '...', 'us-east-1') {
}
}
</pre>

<pre>
java.lang.IllegalArgumentException: No enum constant com.amazonaws.regions.Regions.us-east-1

Changing above to US_EAST_1 to match com.amazonaws.regions.Regions fails because that doesn't match the REGIONS list in S3BucketPublisherContext.groovy.
