[Kibana] Support plugin installation

[diversario]

Describe the feature:
The pre-deprecated Kibana chart supports plugin installation via chart values. It would be helpful if the new Kibana chart supported that as well.

Describe a specific use case for the feature:
Using Kibana plugins without custom Docker image and/or a custom Helm chart (which add complexity for users).

We are using this kibana chart, but want to use elastalert plugin. Any ideas on when this issue will be fixed?

@Crazybus acording to #51 (comment) , should we do the same for Kibana also?

Yup! This is still the recommended way to install plugins.
