Elasticsearch: Bump Exporter to v1.1.0 (latest/stable tag)

This change updates the Elasticsearch chart for compatibility with
the latest version of the Elasticsearch exporter. There are some
breaking changes between v1.0.1 and v1.1.0 - mainly with how arguments
are handled by the program.

All of the configuration options currently available are now exposed
in values.yaml
