pkg/debian: Fix versioning if upstream is dev/rc

  * Ensure a clean upgrade path on debian:
   * Change the upstream version from 'x.x.x.dev' and 'x.x.x.rcx' to 'x.x.x~dev' and 'x.x.x~rcx'
   * Use UTC instead of local time in the debian version

Create logstash.wrapper

Fixed the problem with the plugins as this no longer works.

Create logstash.conf

Added a default "Logstash.conf" as example and so logstash can actually run once you compile the rpm.
Make 'if "something" not in [nonexistent] { ... }' succeed

My argument is checking for the absence of a value in a field that doesn't
exist should return true, currently it is false.

This fixes the case where an event which has never been tagged now works with
this logic:

    grok {
      ...
    }
    if "_grokparsefailure" not in [tags] {
      ...
    }
Added optional username and password to elasticsearch_http output plugin. Fixes LOGSTASH-902.
Small enhancements to netflow codec

- Add configurable target field for netflow fields, defaults to "netflow"
- Add configurable filter to restrict which versions to accept
Setup a periodic filter flush thread.

This got lost in 9542246 and unbreaks LOGSTASH-1284.
