vmagent: expose metric vmagent_remotewrite_queues (#2871) 
The new metric `vmagent_remotewrite_queues` exports a static value of
number of configured remote write queus. This metric is useful to
calculate total saturation per each configured URL with given number
of queues. See corresponding changes to vmagent alerts and dashboard.

app/vmagent add metric for rate limit (#2521) 
This adds a metric for the rate limit.
The limit is present as a flag currently:
`flag{name="remoteWrite.rateLimit", value="500000", is_set="true"} 1`

We are running many instances of vmagent and when creating alerts it is harder than it needs to be when extracting the value from the flag.

With this change it should be easier to monitor how close to the limit we are.

`((100/vmagent_remotewrite_rate_limit{account="account"})*sum (rate(vmagent_remotewrite_conn_bytes_written_total{account="account"}))) and ON (account) flag{name="remoteWrite.rateLimit"} == 1`
