Installing logstash-filter-collate fails:  
logstash-plugin install --version 2.0.4 logstash-filter-collate

It seems that the plugin has a dependency on logstash-core-plugin-api (~\> 1.0) while I have the following gem installed:  
logstash-core-plugin-api (= 2.1.12)

The problem seems to be similar with another isssue ([Logstash-filter-prune gem dependencies](https://discuss.elastic.co/t/logstash-filter-prune-gem-dependencies/64136))

I would suggest to change the gemspec from:  
s.add\_runtime\_dependency "logstash-core-plugin-api", "~\> 1.0"  
to  
s.add\_runtime\_dependency 'logstash-core-plugin-api', '\>= 1.60', '\<= 2.99'

Is it the correct diagnostic?

This plugin needs to be updated to the [new event api](https://www.elastic.co/guide/en/logstash/current/event-api.html), the transition is quite simple, do you want to create a PR and I'll review and merge?
