it doesn't need to be a double right? an integer is still fine. do we even need the tooltip now? Or if you want to add it, you could make it "Threshold can be an integer or a float"

double precision number could be integer or float right?
And, if you type in 3.14159265358979323846264338327950288419716939937510 it will be truncated to 3.141592653589793 by backend. I think it is necessary to let users know there is a limit.

This test is for the old alerts code base. This test can be added here: https://github.com/apache/superset/blob/master/tests/integration_tests/reports/commands_tests.py#L414

Optional (but would be great). Adding integration API tests to assert bad and good validator_config_json

"description, query, validator_type, config",
