lib/promscrape: properly implement ScrapeConfig.clone()
Previously ScrapeConfig.clone() was improperly copying promauth.Secret fields -
their contents was replaced with `<secret>` value.

This led to inability to use passwords and secrets in `-promscrape.config` file.
The bug has been introduced in v1.77.0 in the commit 67b10896d2

lib/mergeset: move storageBlock from inmemoryPart to a sync.Pool
The lifetime of storageBlock is much shorter comparing to the lifetime of inmemoryPart,
so sync.Pool usage should reduce overall memory usage and improve performance
because of better locality of reference when marshaling inmemoryBlock to inmemoryPart.

lib/mergeset: remove superflouos sorting of inmemoryBlock.data at inmemoryBlock.sort()
There is no need to sort the underlying data according to sorted items there.
This should reduce cpu usage when registering new time series in `indexdb`.

Consul SD - update services on the watcher's start (#2202)
* lib/discovery/consul: update services on the watcher's start

Previously, watcher's start was only initing goroutines for discovery
but not waiting for the first iteration to end. It means first Consul
discovery wasn't returning discovered targets until the next iteration.

The change makes the watcher's start blocking until we get first discovery
iteration done and all registries updated.

* vmalert: remove workarounds for consul SD

Now when consul SD lib properly updates services
on the first start, we don't need workarounds in vmalert.

* lib/discovery/consul: update after review
