Error: retry.tryForTime timeout: Error: expected testSubject(mlFileImportSuccessCallout) to exist

This test probably fails because of a missing ES backport of elastic/elasticsearch#61324.
So this is 7.x/7.10 only.

Disabled the file data visualizer tests until the ES backport is in (or the Kibana part that is based on that backport is reverted).

7.x/7.10: ba7c9f9

Tests re-enabled in #77141
