Add elasticsearch

[ningyougang]

• [x] Add activation store backend: ElasticSearch
• [x] Support external elasticsearch
• [x] Add document

Refer to:

• Implement an ElasticSearchActivationStore: https://github.com/apache/openwhisk/pull/4724
• elasticsearch in helm: https://github.com/elastic/helm-charts

I tested below scenes, worked well (after executed wsk -i action invoke ${action}, can get activation successfully using wsk -i activation get ${activationId})

• Use default activation store backend: CouchDB
• Use activation store backend: ElasticSearch (create elasticsearch pod)
• Use external ElasticSearch for activation store

As the error said, Elasticsearch cannot access the underlying file.

java.nio.file.AccessDeniedException: /usr/share/elasticsearch/data/nodes

You need to look into why it cannot access it.
