Go Client - Get all counter vec label vales

[Alex Chaplianka]

I have a CounterVec object, I'm looking for a way to get all of it's labelsets.

For example in the /metric endpoint I can see

my_metric{a="b",k="d"}

my_meric{a="c"}

How could get those labels?:

{a="b", k="d"}

{a="c"}

There is no easy way of doing this (which is deliberate – inspecting
internal state is not an intended part of the exposed interfaces).

But you can do the following:

Call the `Collect` method of the `CounterVec`. Then call the `Write`
method of each `Metric` collected. This gives you `dto.Metric`
structs, which have a `Label` field of type `[]*dto.LabelPair`, which
are the labels you are looking for.

Example of code using a similar approach (in this case to return the
value of a metric):
