Currently, the lastest version is **2.7**. But the version in web page is **2.0**.
So this commit aims to update the URL to the latest version of **prometheus.io**

The previous code was defective in that it never sorted groups within a
file due to doing a multi-key sort incorrectly.

Currently, when we access the modified pages with **HTTP**, it is
redirected to **HTTPS** automatically. So this commit aims to
replace **HTTP** to **HTTPs** for security.

https://github.com/miekg/dns/pull/815 goes into the detail, but more or
less the existing solution was no longer supported and needed to be
rewritten to support the new versions of the library. miekg additionally
claims this is more correct in the ticket.

Now that we have time and size base retention time bases should not have a default value. A default is set only when both - time and size flags are not set.
This change will not affect current installations that rely on the default time based value, and will avoid confusions when only the size retention is set and it is expected that the default time based setting would be no longer in place.

- Remove datarace in the exported highest scrape timestamp.
- Backoff on enqueue should be per-sample - reset the result for each sample.
- Remove diffKeys, unused ctx and cancelfunc in WALWatcher, 'name' from writeTo interface, and pass it to constructor.
- Reorder functions in WALWatcher depth-first according to call graph.
- Fix vendor/modules.txt.
- Split out the various timer periods into consts at the top of the file.
- Move w.currentSegmentMetric.Set close to where we set the currentSegment.
- Combine r.Next() and isClosed(w.quit) into a single loop.
- Unnest some ifs in WALWatcher.watch, propagate erros in decodeRecord, add some new lines to make it easier to read.
- Reorganise checkpoint handling to reduce nesting and make it easier to follow.

This change switches the remote_write API to use the TSDB WAL. This should reduce memory usage and prevent sample loss when the remote end point is down.
We use the new LiveReader from TSDB to tail WAL segments. Logic for finding the tracking segment is included in this PR. The WAL is tailed once for each remote_write endpoint specified. Reading from the segment is based on a ticker rather than relying on fsnotify write events, which were found to be complicated and unreliable in early prototypes.
Enqueuing a sample for sending via remote_write can now block, to provide back pressure. Queues are still required to acheive parallelism and batching. We have updated the queue config based on new defaults for queue capacity and pending samples values - much smaller values are now possible. The remote_write resharding code has been updated to prevent deadlocks, and extra tests have been added for these cases.
As part of this change, we attempt to guarantee that samples are not lost; however this initial version doesn't guarantee this across Prometheus restarts or non-retryable errors from the remote end (eg 400s).
This changes also includes the following optimisations:
- only marshal the proto request once, not once per retry
- maintain a single copy of the labels for given series to reduce GC pressure
Other minor tweaks:
- only reshard if we've also successfully sent recently
- add pending samples, latest sent timestamp, WAL events processed metrics
