When a remote-write is executed towards a host name that is resolved to multiple IP addresses, this PR introduces a possibility to force creation of new connections used for the remote-write request to a randomly chosen IP address from the ones corresponding to the host name. The default behavior remains unchanged, i.s., the IP address used for the connection creation remains the one chosen by Go.
This is an experimental feature, it is disabled by default.

It was crashing due to uninitialized metrics, and not terminating due to
incorrectly reading segment names.
We need to export `SetMetrics` to avoid the first problem.

When we had a syntax error but restored the old file, we did not
re-trigger the config reload, so the config reload metric was showing
that config reload was unsucessful.
I made magic to handle logs in cmd/prometheus.
For now it is a separate file so we can backport this easily.
I will generalize the helper in another PR.

Move a couple of variables inside the scope of a goroutine, to avoid
data races.
Use `zeropool` to reduce garbage and avoid some lint warnings.

Previously, top-level initialization (including WAL reading) had this at
the top of the stack:
github.com/oklog/run.(*Group).Run.func1:38
I found this confusing, and thought it had something to do with logging.
Introducing another local function should make this clearer.
Also make the error message user-centric not code-centric.
