2016-03-06 sysutils/logstash-contrib: Upstream now distributing plugins
separately: see https://github.com/logstash-plugins

Update to 1.4.5 and deprecate

Upstream has changed the way they distribute logstash plugins.  There
are now separate github repos for each individual plugin.  See
https://github.com/logstash-plugins Therefore, upgrade to the latest
available combined version, but also mark the port deprecated and due
to be removed in March.  Individual plugins should be ported as
required.

Update ports in the remaining categories to not use GH_COMMIT.

With minor cleanups to make things simpler.

First there are too many files called zeromq.rb, then there are too
few.  Dammit.

Let's not break the pkg-plist either.

There's a zeromq.rb file with the same contents already in the main
logstash port.  Not conflicting with logstash-1.4.2 is good.

Logstash Contrib Repository

This is a collection of companion plugins (and hopefully tests, too!)
to be used in conjunction with Logstash.

The plugins here are maintained by the core Logstash team, and
supported by the community.
