Bryan Boreham 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.

Bryan Boreham 0289dd6157 relabel: blank replacement deletes label post-regexp
If `cfg.TargetLabel` is a template like `$1`, it won't match any labels,
so no point calling `lb.Del` with it.

Similarly if `target` is not a valid label name, it won't match any
labels, so don't call with that either.

The intention seems to have been that a blank _value_ would delete the
target, so change that code to use `target` instead of `cfg.TargetLabel`.

Bryan Boreham 000182e4b8 relabel: check validity of all test cases
Thought this would be a nice check on the `Validate()` function, but
some of the test cases needed tweaking to pass.

Bryan Boreham 2d4c367d87 relabel: stricter check that target labels are valid
For `Lowercase`, `KeepEqual`, etc., we do not expand a regexp, so
the target label name must not contain anything like `${1}`.

Also for the common case that the `Replace` target does not require any
template expansion, check that the entire string passes label name
validity rules.

Enable reusing memory when converting between histogram types
The 'ToFloat' method on integer histograms currently allocates new memory
each time it is called.

This commit adds an optional *FloatHistogram parameter that can be used
to reuse span and bucket slices. It is up to the caller to make sure the
input float histogram is not used anymore after the call.

A few methods now call `Range()` instead of `range`, but nothing

Fix error on ingesting out-of-order exemplars (#13021)
Fix and improve ingesting exemplars for native histograms.

See code comment for a detailed explanation of the algorithm.

Note that this changes the current behavior for all kind of samples slightly: We now allow exemplars with the same timestamp as during the last scrape if the value or the labels have changed.

Also note that we now do not ingest exemplars without timestamps for native histograms anymore.

add generic shrink function (#13001)
Add `ReduceResolution` method to `Histogram` and `FloatHistogram`

This takes the original `mergeToSchema` function and turns it into a more generic `reduceResolution` function, which is the building block for the new methods.

The methods will help with addressing #12864.
