Backport PR #247 to 8.x: Logging improvements when plugin version mismatches with connected ES version

[github-actions]

Backport PR #247 to 8.x branch, original message:

---

Description

Plugin aligns with stack {major.minor} now. This gives an opportunity to highlight in the logs if plugin is running against the different ES version from the version plugin is built.
This PR considers:

• Connected ES is newer major (warn: pipelines using new features won't work)
• Connected ES is older major (warn: pipelines using deprecated-in-old-major removed-in-new-major options will fail to load)
• Connected ES is same major, but:
  • Connected ES is newer minor (warn: pipelines using new features won't work)
  • Connected ES is older minor (info: low-risk mismatch)
  • Connected ES is same minor (debug: everything is okay)
