Add discovery.ec2.tag and similar to elasticsearch.yml

Great cookbook ! It has been very useful to me.

A support for discovery.ec2.tag filters would be great too.

Thx

Absolutely -- will need to add discovery.ec2.groups and all the related stuff as well.

[thomasmhr]

I may be wrong but you already support discovery.ec2.groups. Tags no (not yet ;-)) but groups you do.

Grr, yes, I have meant cloud.node.auto_attributes
