Remove dependency on dropwizard due to license incompatibility

[richardcloudsoft]

A handful of Brooklyn projects depend on dropwizard. Dropwizard has this chain of dependencies (edited for brevity):

[INFO] \- com.yammer.dropwizard:dropwizard-testing:jar:0.4.4:test
[INFO]    +- com.yammer.dropwizard:dropwizard-core:jar:0.4.4:test
[INFO]    |  +- org.hibernate:hibernate-validator:jar:4.3.0.Final:test
[INFO]    |  |  \- org.jboss.logging:jboss-logging:jar:3.1.0.CR2:test

jboss-logging v3.1.0.CR2 is licensed under the LGPL. This license is incompatible with the Apache License v2 used by Brooklyn - see https://www.apache.org/legal/resolved.html#category-x.

jboss-logging changed its license to Apache v2 in version 3.1.2.GA, but unfortunately even the dropwizard source code head still depends on a jboss-logging version that predates the license change.

dropwizard is used for standing up the web server with the right modules. tedious to redo it another way but shouldn't be hard.

alternatively dropwizard would probably accept a PR to use 3.1.2 GA.

or actually the easiest thing might be to use maven to point at 3.1.2 GA instead of 3.1.0 CR2 ... assuming they are compatible.
