Replace deprecated github.com/golang/protobuf package ( #1183 )
...
This replaces usage of proto.{Float64,Int32,Int64,String,Uint32,Uint64},
which doesn't break the interface.
And remove usage of proto.MarshalTextString in wrap_test.go
Updates: #1175

Add constrained labels and Constrained variant for all MetricVecs ( #1151 )
...
* Introduce MetricVecOpts and add constraints to VariableLabels
MetricVecOpts exposes options specific to MetricVec initialisation. The
first option exposed by MetricVecOpts are constraints on VariableLabels,
allowing restrictions on the possible values a label can take, to
prevent cardinality explosion when the label value comes from a
non-trusted source (as a user input or HTTP header).

Remove spurious commas from links to the docs site

I assume older Nanoc versions rendered the anchors with commas, but
the current doesn't.
Also, this adds the same link to another doc comment where it is also

Add lint:ignore for protobuf deprecation
...
`github.com/golang/protobuf/proto` is deprecated in lieu of
`google.golang.org/protobuf/proto`. However, we cannot simply
migrate. Types from the proto package are exposed to users of packages
in this repo. If we migrate here, users have to migrate to. Thus, we
could only migrate with a major version bump.
In different news, with all the inline lint:ignore comments, including
the existing ones, there is no need to repeat the exception in the
Makefile.
A current version of `staticcheck` is happy with the code after this
commit. golangci-lint is broken at the moment, however, and ignores
the lint:ignore comments in the code as well as those via envvar.
