[Backport 7.56.x] Revert "[dbm] fix flapping sqlserver_version"

[datadog-agent-integrations-bot]

Backport ecf7534 from #18249.

---

Reverts #17750

Reverting this PR as it contains a very bad bug where the host field on metrics and events will fall back to None when the static information cache reaches its TTL of 1 day. When this happens, we see gaps in data for sqlserver instances because our backend drops these as bad payloads. We can see an example of this happening in our integration environment:

... meanwhile, if we log the payloads we see the host value is set to null:

{"host":null,"ddagentversion":"7.56.0","ddsource":"sqlserver",...

A follow up PR will be merged to fix the version tag issue in a subsequent release #18237
