Update pom.xml

Firstly, in time honored tradition - the maven enforcer plugin crashes with a null pointer exception, compatibility hasn't been maintained by the Apache team in their latest product iteration. As far as I can see, the sole purpose of this plugin is to enforce the use of Maven 3.0 during builds - Maven 3.0 is obsolete btw.

Secondly, the enforcer is enforcing that folk use Maven 3.0 :

From the Maven project - "Apache Maven 3.5.2 is the latest release and recommended version for all users."

Thirdly:

Warnings as errors - warning wrt conversion/use of Long in riak/client/core/query/timeseries/DescribeQueryResultParser.java breaks the build - it's deprecated as of Java 9 (installed by default on OSX). IMHO - at this point in product life-cycle better to generate a warning and have folk build the project than fail on something that will be a (potential) issue come Java 10 (and it's debatable whether there's any point in keeping the Riak TS code anyway).

Discovered sooooo many other things that broke on maven 3.5/java 9. I'm going to create a proper feature branch and make a larger pull request. people were lovin' those internal API's, powermock version is incompatible with Java 9 (hitting lots of illegal accesses), uh, pulling in random javax xml api to perform hex encoding, mocking stuff - then not hitting the mock, etc. Anyway bigger p/r coming very soon.
