* TSDB: demistify seriesRefs and ChunkRefs
The TSDB package contains many types of series and chunk references,
all shrouded in uint types. Often the same uint value may
actually mean one of different types, in non-obvious ways.
This PR aims to clarify the code and help navigating to relevant docs,
usage, etc much quicker.
Concretely:
* Use appropriately named types and document their semantics and
relations.
* Make multiplexing and demuxing of types explicit
(on the boundaries between concrete implementations and generic
interfaces).
* Casting between different types should be free. None of the changes
should have any impact on how the code runs.
TODO: Implement BlockSeriesRef where appropriate (for a future PR)

The compaction analysis which runs under promtool tsdb analyze can be an
intensive process which slows down the entire command.
This commit adds an --extended flag to tsdb analyze which can be toggled
for running long running tasks, such as compaction analysis.

* Extend promtool to support compaction analysis
This commit extends the promtool tsdb analyze command to help
troubleshoot high Prometheus disk usage. The command now plots a
distribution of how full chunks are relative to the maximum capacity of
120 samples per chunk.

* promtool: backfill: allow configuring block duration
When backfilling large amounts of data across long periods of time, it
may in certain circumstances be useful to use a longer block duration to
increase the efficiency and speed of the backfilling process. This patch
adds a flag --block-duration-power to allow a user to choose the power N
where the block duration is 2^(N+1)h.

* backfill: test long block durations
A test that uses a long block duration to write bigger blocks is added.
The check to make sure all blocks are the default duration is removed.
Signed-off-by: Steve Kuznetsov <skuznets@redhat.com>
When using the backfill command to add data to an ephemeral/test
Prometheus instance, it is not important to see which data was added as
it is often generated ahead of time and mostly irrelevant to the
use-case. The current approach prints information about each block that
is written, but does so in a generally inefficient and costly manner.
This patch adds a `--quiet` flag that allows a user to opt out of this
behavior.

By default same value that was hardcoded is used, but with the
new flag added the number of scrapes can be increased to any value.
Signed-off-by: Pau Freixes <pfreixes@gmail.com>
This moves the label lookup into TSDB, whilst still keeping the cached-ref optimisation for repeated Appends.
This makes the API easier to consume and implement. In particular this change is motivated by the scrape-time-aggregation work, which I don't think is possible to implement without it as it needs access to label values.

When printing the error, we still need access to the mmapped byte array
of the file. Therefore, we make sure that we run it before closing the
file.
I could have done something more complex like a defer, or not closing
the file, knowing that we would exit the program anyway. However, I
think that in case we extend this in the future, or this is copy/paster
elsewhere, we should continue closing the file. As it is small enough, I
went for the solution to call the function 3 times instead of playing
with a defer.

I initially thought I could somehow rescue the current column layout
by recycling the tabwriter, but flushing completely blanks
it. However, by setting a minimum width of 13, we get a slightly
broader DURATION column but otherwise nice formatting, unless numbers
get really big, but that's OK, I guess.
Before:
```
