The buffers we allocated were escaping to the heap, resulting in large
memory usage spikes during startup and checkpointing in Prometheus.
This attaches the buffer to the reader object to prevent this.

We assume in multiple places that the block list held by DB
has blocks sequential by time.
A regression caused us to hold them ordered by ULID, i.e. by creation
time instead.

Create checkpoints from a sequence of WAL segments while filtering
out obsolete data. The checkpoint format is again a sequence of WAL
segments, which allows us to reuse the serialization format and
implementation.

Allow to repair the WAL based on the error returned by a reader
during a full scan over all records.

This adds a new WAL that's agnostic to the actual record contents.
It's much simpler and should be more resilient than the existing one.

Allowing to set a custom endpoint makes it easy to monitor targets on non AWS providers with EC2 compliant APIs.

Sorry, I used GitHub's web-based merge-conflict-resolution editor on
https://github.com/prometheus/prometheus/pull/4308 and it didn't show me
test errors afterwards, but maybe they didn't run again or I should have
waited or something.

`debug all` - all information
`debug metrics` - metrics information
`debug pprof` - profiling information
the final result is compressed in a `tar.gz` file

* Allow for BufferedSeriesIterator instances to be created without an underlying iterator, to simplify their usage.

* Add Start/End to SelectParams
* Make remote read use the new selectParams for start/end
This commit will continue sending the start/end time of the remote read
query as the overarching promql time and the specific range of data that
the query is intersted in receiving a response to is now part of the
ReadHints (upstream discussion in #4226).
* Remove unused vendored code
The genproto.sh script was updated, but the code wasn't regenerated.
This simply removes the vendored deps that are no longer part of the
codegen output.

Start rule manager only after tsdb and config is loaded.
Stop rule manager before tsdb to avoid writing to closed storage.
Wait for any in-progress reloads to complete before shutting
down rule manager, so that rule manager doesn't get updated after
being shut down.
Remove incorrect comment around shutting down query enginge.
Log when config reload is completed.
