Instead of reading a generic-ish `[]string` slice, we can read a generic type which would be specifically `labels.Label` for the posting offset table. This avoids allocating a slice that escapes...

Make query-frontend cache TTL configurable, and increase the default.

### What happened? I called `config.Configuration.InitGlobalTracer(...)` after replacing the `http.DefaultTransport` with a custom implementation, and it panicked. The code assumes that `http.DefaultTransport` is a `*http.Transport`, and panics otherwise: https://github.com/jaegertracing/jaeger-client-go/blob/8d8e8fcfd04de42b8482476abac6a902fca47c18/sampler_remote.go#L308 ###...
