RepeatedTask metric labels are incorrect

wisp/wisp-task/src/main/kotlin/wisp/task/RepeatedTaskMetrics.kt

Line 20 in 98ed57d

.tag("name", "result")

looks like it's trying to add two labels to the metric, name and result. There are two problems here:

that tag method actually takes key and value parameters, so we are adding one label named name and recording the value result
there's no attempt to pass correct tags when recording the metric in https://github.com/cashapp/wisp/blob/main/wisp-task/src/main/kotlin/wisp/task/RepeatedTask.kt#L108

I've been trying to write a pull request that fixes this and adds tests that metrics are being recorded as expected, but I am having a very difficult time getting a usable metric registry in unit tests.

@chris-ryan-square Are there any examples of validating metrics in unit tests for wisp that I can follow?

Not that I am aware of - I think the only reference to metrics is in wisp-task
