feat(elasticsearch): add Elasticsearch workflows (#154)

* feat(elasticsearch): add Elasticsearch workflows

Add a few simple Elasticsearch workflows, such as

* check connection to ES
* show cluster health
* list indices
* count documents in index

* docs(elasticsearch): add source urls to commands

Since it looks like the source url is important in other pull requests, I have added links to the documentation for the commands that offer extra arguments.

Also added author url, if that might also be required.

* fix(elasticsearch): remove connection check workflow, as curl workflow can be used
