In general aim for the happy case when the exposer lists the buckets
in ascending order.

Use Compact(2) to compact the result of nhcb convert.

This is more in line with how client_golang optimizes spans vs
buckets.

The wrong source was used to return the created timestamp, leading to
index out of bound panic. One line fix.

Refactor the requirement test to be generic and be able to
test OpenMetrics and Prom parsers as well.
There are some differencies in what the parsers support, the Prom
parser doesn't have created timestamp.

The protobuf parser uses different formatting to identify the metric
for the scrape loop.
Each parser represents the sample timestamp differently.

Call through to the underlaying parser if we are not in a histogram
and the entry is a series or exponential native histogram. Otherwise store
and retrieve CT for NHCB.

* fix(omparser): losing exemplars when CT is parsed

Fixes: #15137
Ignore exemplars while peeking ahead during CT parsing.
Simplify state reset with defer().

Very high level since we'll do a lot of optimizations so not
worth going into details at this time.
