Add elasticsearch cli tool

[gnz00]

What changed?

• A new elasticsearch-cli-tool that replaces curl invocations
• ClusterPutSettings and Ping methods added to the ES client wrappers

Why?
Currently, there are scripts referenced in the dockerfiles and the helm charts that rely on curl to create ES indices and poll for ES availability, e.g.

https://github.com/temporalio/docker-builds/blob/main/docker/auto-setup.sh#L245-L263
https://github.com/temporalio/docker-builds/blob/main/docker/auto-setup.sh#L265-L278
https://github.com/temporalio/temporal/blob/master/Makefile#L372-L377
https://github.com/temporalio/helm-charts/blob/master/templates/server-job.yaml#L281
https://github.com/temporalio/helm-charts/blob/master/templates/server-job.yaml#L288-L289
https://github.com/temporalio/helm-charts/blob/master/templates/server-deployment.yaml#L76

It would be better if there was a tool that leveraged the built-in temporal ES auth providers (#1011) and a place to put common ES operations

How did you test it?

• Verified the tool using a new AWS Opensearch domain running Elasticsearch 7.10
• Ran the test suites

Potential risks

• An additional tool to maintain
• May be a better place for this
• Curl supports AWSv4 signature signing, but this would allow other providers to be implemented and keep things consistent with the core temporal ES auth provider implementation

Is hotfix candidate?
No

😮 this is great! I've never had time for it and honestly curl was good enough. Is the auth a main motivation for you? I need to review this.

Hah, yea I'm trying to write a Terraform module that can deploy to an AWS stack with RDS + Opensearch. The necessary piece was #2830, but this will allow me to avoid having to wrap the Dockerfile or modify the helm-chart. I'll have to PR both of those with some adjustments I've made for these changes as well.
