use bundler compatible ruby version string

ES version 1.0 or greater is now supported by all protocols.

The Elasticsearch eng team has tests to ensure client nodes from all ES versions >=1.0 work with all ES clusters version >=1.0

Closes elastic#1380

Update the example because output doesn't have the message parameter, instead it should use a a codec.
Also update the way how logstash is executed.

Tilde '~' is a valid character in UNIXPATHs.

Tests included.

Note about grammar compilation:
  I had to use treetop 1.4.15 (1.5.3 generates ruby code that fails to
  parse, haven't spent any time debugging)

To avoid issues like:

/etc/cron.daily/logrotate:
gzip: stdin: file size changed while zipping

This change is harmless and will prevent errors like this one

Update Gemfile for package testing

Remove the log parameter as web doesn't allow it

Add sprintf ability to room_id field in hipchat output

- Use better installer method to avoid documentation installation
  With the previous method it would install the documentation which didn't exist.

- Create Fake gemspec info for logstash to help dependency management for plugins
  Previously we would create a real gem and install it to aid in dependency management for plugins and logstash
  Now we create a fake gemspec on the fly with the real version of logstash avoiding having to build it every time.

Previously the loading of the logstash gemspec was limited to the plugin manager
After more tests we need the gemspec to be loaded for any action with the plugins
Moving it to the environment module makes it available for more generic loading

Make sure plugin manager uses new function for loading gemspec

Addresses elastic#1747.
This removes the argument list iteration and spawning of multiple
tasks.
It's still possible to specify aditional arguments but now they're
ignored.

The filter should only modify the event's fields and tags if and only if
all resolves/reverses succeed. So we clone the event, modify the new
copy and return it if all operations succeed. Otherwise the original
event is not modified.

For performance reasons we could reverse the clone logic: clone the
event, modify the original event and, it case of failure, return the
backup.

Note: this changes the dns filter behaviour towards add_tag
