Updated resteasy version

[Graeme-Miller]

This is successor to this PR.
After the rest client was moved to brooklyn-client in this PR two new PRs had to be created, one for brooklyn-server and one for brooklyn-client.

Please merge this PR at the same time.

This PR updates resteasy to 3.0.14.Final.

[Graeme-Miller]

Test failures are because brooklyn-client relies on brooklyn-rest-api which pulls in an older verision of jackson.

All tests pass locally when apache/brooklyn-server#339 is included.

@Graeme-Miller this change won't be needed if #27 is merged.

@Graeme-Miller Can you explain why we're upgrading to resteasy 3.0.14.Final? There is a 3.0.19.Final available - why not upgrade to that?

TL;DR we don't bundle brooklyn-rest-client with the Brooklyn distro, so I think we can ignore the version difference discussed below.

I see that resteasy depends on com.fasterxml.jackson version 2.6.3 (the previous resteasy resteasy 3.0.8 depended on fasterxml version 2.3.2).

However, in apache/brooklyn-server#339, you're upgrading com.fasterxml.jackson from 2.4.5 to 2.7.5. That means mvn is trying to pull in two different versions of fasterxml. That's manageable in Karaf (though not ideal), but is a pain with the vanilla Java main. We'd need to have <excludes> to ensure we get the right single version.

I see that resteasy has a 3.1.0.Beta2 available, which depends on fasterxml 2.7.4. It came out on 9th September 2016; the Beta1 was on 28th July 2016. That depends on fasterxml 2.7.4. It took 6 beta releases before a 3.0.0-rc1 and then 3.0.0.Final, so we shouldn't hold our breath!
