Add WithExplicitBucketBoundaries Histogram option to the metric api

[dashpole]

Part of #4094

I split the API changes into its own PR so we can discuss them independently. There are a few choices we have:

One option or two (for int vs float)

Single Option (proposed):

  func WithExplicitBucketBoundaries(bounds []float64) HistogramOption
  type HistogramOption interface {
  	Int64HistogramOption
  	Float64HistogramOption
  }

VS

 func WithFloat64HistogramBoundaries(boundaries []float64) Float64HistogramOption
 func WithInt64HistogramBoundaries(boundaries []float64) Int64HistogramOption

[]float64 vs ...float64

UX of ...float64 (proposed)

  histogram, err := meter.Float64Histogram(
	"task.duration",
	metric.WithExplicitBucketBoundaries(.005, .01, .025, .05, .075, .1, .25, .5, .75, 1, 2.5, 5, 7.5, 10),
  )

UX of []float64:

 histogram, err := meter.Float64Histogram(
   "task.duration",
   metric.WithExplicitBucketBoundaries([]float64{.005, .01, .025, .05, .075, .1, .25, .5, .75, 1, 2.5, 5, 7.5, 10}),
)
