Can't see why do we need to hold a mutex on symbols, and the purpose of

Maybe I'll need to re-add this later.

* Implement LabelNamesFor
This method provides the label names that appear in the postings
provided. We do that deeper than the label values because we know
beforehand that most of the label names we'll be the same across
different postings, and we don't want to go down an up looking up the
same symbols for all different series.

It's a prefectly valid use case to have a sparse histogram with a zero
threshold of zero (i.e. only observations of exactly zero go into the
zero bucket). Even if the current PoC implementation of client_golang
doesn't allow that, such a case should be ingested properly.
However, there is now the edge case af a sparse histogram with a zero
threshold of zero and no observations yet. Such a histogram would look
the same if it was meant to be a conventional histogram. For now, we
ingest this case as a conventional histogram, but the final format
should have means to unambiguously express if a histogram is meant to
be ingested as a sparse histogram or as a conventional histogram.

Parser now supports summaries and legacy histograms including
exemplars.
It also adds the option of specifying exemplars together with a sparse
histogram by simply using the legacy bucket section, too. The buckets
will be ignored, but the exemplars will be ingested.

An opinionated cosmetic change, but since go 1.13 we have this fancy
