check-es-cluster-health warning ::Fixnum

[jothoma1]

Hello,
i'm using your plugins with sensu 1.0 and the check-es-cluster-health.rb return a warning :

/opt/sensu/embedded/lib/ruby/gems/2.4.0/gems/elasticsearch-transport-1.0.18/lib/elasticsearch/transport/transport/base.rb:52: warning: constant ::Fixnum is deprecated
/opt/sensu/embedded/lib/ruby/gems/2.4.0/gems/elasticsearch-transport-1.0.18/lib/elasticsearch/transport/transport/base.rb:54: warning: constant ::Fixnum is deprecated
ESClusterHealth CRITICAL: Cluster state is Red

Thanks in advance

This will be affecting anyone using this plugin on Ruby 2.4.0; caused by the dependency on the elasticsearch gem. It looks like it's already been fixed upstream however this plugin pins an older version of the gem.

@majormoses You're probably already aware but one to note for the 2.4.1 testing -- To resolve this issue I assume it'll require bumping to use the latest major release (5.) of the elasticsearch gem.

In the meantime @jothoma1 you could export the below to suppress these warnings:

RUBYOPT=-W0

i.e.

command 'RUBYOPT=-W0 /opt/sensu/embedded/bin/check-es-cluster-status.rb' 

EDIT: I see related discussion #48

I checked and we can bump to 2.x when I have some time I can try bumping this I am more concerned about the lack of testing in this plugin so it will require lots of testing against multiple versions of ES so we know what breaks on what versions.

#73 for adding tests.
