Increase Netty 3 REST test suite timeout

This commit increases the Netty 3 REST test suite timeout to thirty
minutes. This is to address these tests running slowly after increasing
the number of nodes in the tests to two. This has surfaced that the
tests are heavily impacted by excessive fsyncs from most tests using the
default number of shards of five.
