[ML] Anomaly Detection: Fix validation error when no data in index. (e…

For cardinality checks, an empty index of the fields checks not returning any results would block the user from moving to the next step in the Anomaly Detection job wizard.
This PR fixes it by adding more fine grained checks and only returning warning-level messages for the above cases. A warning-level message will allow the user to continue to the next step in the wizard.
