* Fixup PROMU unpack
When setting up promu, use an explicit path, not the `PROMU` variable.
This allows for Makefile override of the PROMU command line flags.
* Use temp dir for unpacking tools.
* Use BSD compatible tar command.
* OpenBSD mkdir doesn't support `-v`.

* refactor NewSegmentsRangeReader to take multi WAL ranges
In case of an error when checkpointing the WAL the error doesn't show
the exact WAL index that is corrupter. this is because it uses
MultiReader to read multiply WAL files.
This refactoring allows the NewSegmentsRangeReader to take more than a
single WAL range and it reads all of the ranges by iterating each one.
this changes the logs from
create checkpoint: read segments: corruption after 4841144384 bytes:...
to
create checkpoint: read segments: corruption in segment
data/wal/00017351 at 123142208: ...

* repair wal when the record cannot be decoded
Currently repair is run only when the error happens in the reader.
A corruption can occur after the record is read and when it is decoded.
This change wraps the error at decoding as a CorruptionErr as this error
is expected to trigger a repair.

This causes the head to be GCed at startup,
removing any series that were read from the WAL
but have since been written to a block. In
systems with low ingestion rates, this potentially
could be many many hours of data.

Fixes#4855 - ServicePort was wrongly used to construct an address to endpoints
defined in portMappings. This was changed to HostPort. Support for obtaining
auto-generated host ports was also added.

When a metric has a null value, number formatters like
`humanizeNoSmallPrefix` will throw "Uncaught TypeError: Cannot read
property 'toPrecision' of null".
This is fixed by explicitly checking for `null` and returning the string
"null".
Note: This is usually not seen as rickshaw doesn't show annotations for
null values, but still calls the formatter.

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.
