Common service discovery mechanisms such as Kubernetes can generate a
lot of target groups, so this function was allocating a lot of memory
which then immediately became garbage. Re-using the structures across
an entire Sync saves effort.

Dumping without any limit on the data being dumped will generate
a large amount of data. Also, sometimes it is necessary to dump
only a part of the data in order to change or transfer it.
This change allows to specify a part of the data to dump and
by default works same as before. (no public API change)

* Add a --lint flag to the promtool check rules and check config commands
Checking rules with promtool emits warnings in the case of duplicate rules.
These warnings do not result in a non-zero exit code and are difficult to
spot in CI environments. Additionally, checking for duplicates is closer
to a lint check rather than a syntax check.
This commit adds a --lint flag to commands which include checking rules.
The flag can be used to enable or disable certain linting options
and cause the execution to return a non-zero exit code in case
those options are not met.

This follows the line of argument that the invariant of not looking
ahead of the query time was merely emerging behavior and not a
documented stable feature. Any query that looks ahead of the query
time was simply invalid before the introduction of the negative offset
and the @ modifier.

This commit adds a `--syntax-only` flag for `promtool check config`.
When passing in this flag, promtool will omit various file existence
checks that would cause the check to fail (e.g. the check would not
fail if `rule_files` files don't exist at their respective paths).
This functionality will allow CI systems to check the syntax of
configs without worrying about referenced files.

* 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.

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.

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.
