The labels need to be passed to `#observe`

Tracking them all in separate histograms would make the PE dashboard
very large and slightly messy

p99 of pipeline creation is generally between 5s and 20s, so adding
additional buckets between that will give us needed insight into step
creation duration.

Because it never jumps, monotonic time is more reliable for creating this data set

Using `2.hours.ago - 1.hour.ago` gives a value that is slightly off from
3600 seconds (and also is a negative number - not a duration). `1.hour`
is more stable and simple to understand

This commit adds instrumentation to track and graph the duration in
seconds of each pipeline creation step in
`::Ci::CreatePipelineService::SEQUENCE`. Each class in the sequence is
tracked as a separate step.
