Base URL as a required parameter in `elasticsearch` data source configuration

[traut]

Description

The base URL is not needed when cloud_id is set, so it should not be a required argument.

Steps to Reproduce

config data elasticsearch {
  cloud_id = "test-cloud-id"
  api_key = ["key-id", "key-value"]
  base_url = "https://localhost.localhost"
}

Expected Behavior

• if both base_url and cloud_id are set, cloud_id value takes precedence and a warning is shown
• if neither base_url nor cloud_id are set, an error is shown

Actual Behavior

When base_url is not set:

$ ./fabric_darwin_arm64/fabric render document.test --plugins-dir ./plugins_darwin_arm64/plugins
Feb 18 14:21:58.214 WRN This is a dev version of the software

Error: Missing required argument

  on 1.fabric line 7, in config "data" "elasticsearch":

The argument "base_url" is required, but no definition was found.

Error: Failed to fetch data

When both base_url and cloud_id are set:

$ ./fabric_darwin_arm64/fabric render document.test --plugins-dir ./plugins_darwin_arm64/plugins
