[Elasticsearch] run 7.0.0-SNAPSHOT versions on 6.6.0-alpha1 chart

[kuisathaverat]

I have tried to use the Helm chart 6.6.0-alpha1 with the Docker image 7.0.0-SNAPSHOT, but it did not find a minimum masters number to start (2), I know it probably does not work but I report it only in case.

I have realized that there is an option to set the major version of elasticsearch

esMajorVersion: 7
