lib/memory: export process_memory_limit_bytes metric, which shows the amounts of memory the current process has access to 
This metric is equivalent to `vm_available_memory_bytes`, but it has better name,
since the metric is related to a process, not VictoriaMetrics itself.

Leave `vm_available_memory_bytes` for backwards compatibility.

lib/mergeset: skip common prefixes when comparing inmemoryBlock items 
This should improve the performance for items sorting inside inmemoryBlock.MarshalUnsortedData
if they have common prefix.

While at it, improve the performance for inmemoryBlock.updateCommonPrefix for sorted items.
This should improve performance for inmemoryBlock.MarshalSortedData during background merge.

lib/{storage,regexpcache}: replaces regexpCacheMap with LRU cache (#2293) 
* lib/{storage,regexpcache}: replaces regexpCacheMap with LRU cache

It should decrease memory usage for regexp caching
with storing cacheEntry by pointer - golang map should be able to effectivly shrink it's size
original issue with this case - unexpected map grows and storage OOM

lib/blockcache: properly remove references to deleted parts 
Previously references to deleted parts may remain active as cache.m keys.
This could prevent from proper memory de-allocation.
This could lead to increased memory usage for the following caches starting from v1.73.0:

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.

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.
