* app/vmagent: allow vm proto for kafka consumer and producer
it should reduce network usage up to 50%.
According to benchmarks without any encoding at kafka topic, it reduces traffic up to 50%.
With enabled zstd at kafka topic, it shows no diffence in traffic. So it
doesn't make much sense to use it.

* vmalert: support concurrent reading from object storage
Config reading from GCS or S3 can be slow if object storage
contains a big number of files. Object storages are usually
fast for downloading and are slow for individual operations.
If there would be thousands of files to read, vmalert could
spend significant time for retrieving those because it is
done sequentially.
The change introduces ability to read configs from object
storage concurrently. By default, both GCS and S3 are now
read with 50 concurrent readers. This significantly reduces
the load time:
* loading 500 files with concurrency=1 takes 27s
* loading 500 files with concurrency=50 takes <1s
* vmalert: add note to Changelog
* vmalert: cleanup
* vmalert: use ticker properly
* app/vmalert: improve status reporting during config loading
