0f760f63dd lint: Revamp our linting rules, mostly around doc comments 
Several things done here:

- Set `max-issues-per-linter` to 0 so that we actually see all linter
  warnings and not just 50 per linter. (As we also set
  `max-same-issues` to 0, I assume this was the intention from the
  beginning.)

- Stop using the golangci-lint default excludes (by setting
  `exclude-use-default: false`. Those are too generous and don't match
  our style conventions. (I have re-added some of the excludes
  explicitly in this commit. See below.)

- Re-add the `errcheck` exclusion we have used so far via the
  defaults.

- Exclude the signature requirement `govet` has for `Seek` methods
  because we use non-standard `Seek` methods a lot. (But we keep other
  requirements, while the default excludes completely disabled the
  check for common method segnatures.)

- Exclude warnings about missing doc comments on exported symbols. (We
  used to be pretty adamant about doc comments, but stopped that at
  some point in the past. By now, we have about 500 missing doc
  comments. We may consider reintroducing this check, but that's
  outside of the scope of this commit. The default excludes of
  golangci-lint essentially ignore doc comments completely.)

- By stop using the default excludes, we now get warnings back on
  malformed doc comments. That's the most impactful change in this
  commit. It does not enforce doc comments (again), but _if_ there is
  a doc comment, it has to have the recommended form. (Most of the
  changes in this commit are fixing this form.)

- Improve wording/spelling of some comments in .golangci.yml, and
  remove an outdated comment.

- Leave `package-comments` inactive, but add a TODO asking if we
  should change that.

- Add a new sub-linter `comment-spacings` (and fix corresponding
  comments), which avoids missing spaces after the leading `//`.

2e30f1231b docs: textparse.Parser return type mismatch 
The docs suggest the Next method returns a bool, but that's not the case (`Entry` is an int).

```
	// Next advances the parser to the next sample. It returns false if no
	// more samples were read or an error occurred.
	Next() (Entry, error)
```

The docs were first added in d80a3de235 in 2017. Back then the signature was
indeed `func (p *Parser) Next() bool`. But then it got refactored in 76a4a46cb0
and the signature changed with it, yet docs stayed the same - and eventually made their way into the `Parser` interface.

However, the Protobuf parser does have the right wording: 5de2df752f

```
// Next advances the parser to the next "sample" (emulating the behavior of a
// text format parser). It returns (EntryInvalid, io.EOF) if no samples were
// read.
```

Changing all other implementations (and the interface itself) to match this doc.

5597020a60 Use github.com/klauspost/compress for gzip and zlib 
klauspost/compress is a high quality drop-in replacement for common Go
compression libraries. Since Prometheus sends out a lot of HTTP requests
that often return compressed output having improved compression
libraries helps to save cpu & memory resources.
On a test Prometheus server I was able to see cpu reduction from 31 to
30 cores.

UTF-8: Add partial support for parsing UTF-8 metric and label names

a28d7865ad UTF-8: Add support for parsing UTF8 metric and label names 
This adds support for the new grammar of `{"metric_name", "l1"="val"}` to promql and some of the exposition formats.
This grammar will also be valid for non-UTF-8 names.
UTF-8 names will not be considered valid unless model.NameValidationScheme is changed.

This does not update the go expfmt parser in text_parse.go, which will be addressed by https://github.com/prometheus/common/issues/554/.

8065bef172 Move metric type definitions to common/model 
They are used in multiple repos, so common is a better place for them.
Several packages now don't depend on `model/textparse`, e.g.
`storage/remote`.

Also remove `metadata` struct from `api.go`, since it was identical to
a struct in the `metadata` package.
