app/vmagent add metric for rate limit (#2521)

Browse source 
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`
