add last run status to checks/rules

[desa]

Similar to tasks, we should return

	LatestCompleted string                 `json:"latestCompleted,omitempty"`
	LatestScheduled time.Time              `json:"latestScheduled,omitempty"`
	LastRunStatus   string                 `json:"lastRunStatus,omitempty"`
	LastRunError    string                 `json:"lastRunError,omitempty"`

for checks and notification rules.

We should display something similar to the tasks UI.

This will involved modifying the checks and notifications UI and API. In the API, we'll need to grab those values from the task that backs the check/rule.

It seems like the changes made to updateCheck weren’t updated here:

https://github.com/influxdata/influxdb/blob/master/ui/src/alerting/components/CheckCard.tsx#L17

Need some clarity from @ebb-tide on how to best go about update the component to accurately reflect the new functionality since the previous implementation seems to be a bit different on might require an overhaul of the way the check data is currently being updated
