Currently Prometheus requests show up with a UA of Go-http-client/1.1
which isn't super helpful. Though the X-Prometheus-Remote-* headers
exist they need to be explicitly configured when logging the request in
order to be able to deduce this is a request originating from
Prometheus. By setting the header we remove this ambiguity and make
default server logs just a bit more useful.
This also updates a few other places to consistently capitalize the 'P'
in the user agent, as well as ensure we set a UA to begin with.

This saves memory, about a quarter of the size of the postings map
itself with high-cardinality labels (not including the post ids).

This reduces memory by only having to store the string's 16
bytes+map overheard once per label name, rather than duplicating it in every
entry for the label value.

Reuse the string already allocated for symbols
in the posting tables.
Use a slice for symbols in v2 format.
Move symbol size logic into the index code.
Avoid duplication of lookupSymbol logic.

This shows up as a hot spot in profiles of queries involving lots of seeks, as each seek creates a new iterator.

change automated compaction can be disabled, but allow to run it
manually it tests.

According to the GoDoc for os.Signal [0]:
> Package signal will not block sending to c: the caller must ensure that

> For a channel used for notification of just one signal value, a buffer

By default the gRPC client of the REST API gateway relies on the
HTTP_PROXY variable to connect to the local gRPC server which isn't
desired as the server runs in the same process. This change uses a
custom dialer that connects directly to the server's address.
