Fix trigger type for OnChange triggers

Triggers with no threshold parameters should be treated as ones that
activate on change of monitored metric values', with `Discrete` property
value set to true. Otherwise they will be wrongly treated as numeric
triggers on Redfish side. This patch corrects this behavior.

Tested:
1. Created simple discrete trigger: `TestTriggerDiscreteOnChange`, with
`DiscreteTriggerCondition` set to `Changed`.
2. busctl introspect xyz.openbmc_project.Telemetry
/xyz/openbmc_project/Telemetry/Triggers/TelemetryService/
    TestTriggerDiscreteOnChange
3. Verified that `Discrete` property is true

All unit tests have passed.
