Previously we were only fetching the version when the version was `0`.
This generally worked, but posed some problems when customers were
updating their Zabbix version, specifically when upgrading from a
version < `7.2.x` to `7.2.x` or above.
Before `7.2.x`, an `auth` parameter was still supported when issuing a
zabbix request, this was deprecated in `6.4.x` and later removed in
`7.2.x`. When a user was on a version < `7.2.x` all the outgoing
requests would add this `auth` parameter. When upgrading to `7.2.x` this
was a problem, because the version was not `0`, hence, not requiring
getting the version again, but also because we were still building the
request considering an older version and adding the `auth` parameter,
when this was no longer supported.
This PR removes the check for `version == 0`, though this now means that
every request that goes out will check the version before hand, I think
this will give us a more accurate representation of the version that
needs to be used.

This PR moves the health check to backend only leaving in the frontend
the functionality to test the dbconnector datasource.
Leaving the `dbconnector.testDataSource` should be fine since the
datasource types we allow for db connection with Zabbix already are
backend datasources, and so their health requests would go through the
backend.
Verified:
Clicking test and seeing a `health` request go out.
IMPORTANT: While testing this in the UI, I found a bug with the config
editor - whenever a change is made in the UI and tested, the changes
don't take effect (i.e. disabling trends, keeps `trends` set to `true`,
enabling db connection keep `dbConnectionEnabled` set to `false` and so
on.). Created a separate
[issue](https://github.com/orgs/grafana/projects/457/views/40?pane=issue&itemId=3627315751&issue=grafana%7Coss-big-tent-squad%7C132)
