Note to reviewers: the server side API endpoint doesn't exist yet. I'm building the support in Mimir following the Loki specs.

This is a NewString function but it returns an existing string. I think this can hide undesired behaviors. Why would we expect this to overwrite a string?

It was copied from Loki, and I just kept logic as is. The way this stat function (and functions that will be introduced in the next PR) are intended to use, is just as a "get or create". I can change the name function to make it more clear.

Offtopic: I feel like this should be done in the BasicService, not in all the service implementers.

AFAIK this does nothing here.

It depends if there are tests with t.Parallel(). For example the two following tests can be executed in parallel:
func TestOne(t *testing.T) {
t.Parallel()
// ...
}
func TestTwo(t *testing.T) {
t.Parallel()
// ...
}
I generally prefer to flag a slow test which is safe to run parallelly with t.Parallel() without worrying if there are other parallel tests. If in the future we'll add them, they will run in parallel.

What this PR does
In this PR I'm adding the logic to periodically send anonymous usage stats report. The report doesn't contain custom metrics yet (will be done in in the next PR). The default stats we send (and the frequency) are the exact same of the ones sent by Loki, to keep consistency.
Which issue(s) this PR fixes or relates to
Part of #1815
