98854e5f2b app/vmselect: add sign(q) and clamp(q, min, max) functions, which will be added in the upcoming Prometheus release 
See https://twitter.com/roidelapluie/status/1363428376162295811

The `last_over_time(m[d])` function already exists in MetricsQL.

901e12024d vendor: update github.com/VictoriaMetrics/metrics from v1.14.0 to v1.15.0 
The v1.15.0 exports the following additional metrics:

    process_io_read_bytes_total - the number of bytes read via io syscalls such as read and pread
    process_io_written_bytes_total - the number of bytes written via io syscalls such as write and pwrite
    process_io_read_syscalls_total - the number of read syscalls such as read and pread
    process_io_write_syscalls_total - the number of write syscalls such as write and pwrite
    process_io_storage_read_bytes_total - the number of bytes read from storage layer
    process_io_storage_written_bytes_total - the number of bytes written to storage layer

These metrics can be used for monitoring process io

636c55b526 lib/mergeset: reduce memory usage for inmemoryBlock by using more compact items representation 
This also should reduce CPU time spent by GC, since inmemoryBlock.items don't have pointers now,
so GC doesn't need visiting them.

48656dcc38 lib/{mergeset,storage}: allow merging smaller number of small parts 
While this may increase CPU and disk IO usage needed for background merge,
this also recudes CPU usage during queries in production. This is because
such queries tend to read recently added data and it is better to have lower number
of parts for such data in order to reduce CPU usage.

This partially reverts ebf8da3730

faad6f84a4 lib/storage: return back filter arg to getMetricIDsForTagFilter function 
The filter arg has been removed in the commit c7ee2fabb8
because it was preventing from caching the number of matching time series per each tf.

Now the cache contains duration for tf execution, so the filter shouldn't break such caching.
