2f612e0c67 app/vminsert: fix relabeling for metrics ingested via Influx line protocol 
Previously the enabled relabeling with `-relabelConfig` command-line flag could result in missing labels
if a single Influx line protocol message contains multiple field values.

6daa5f7500 lib/storage: prioritize data ingestion over heavy queries 
Heavy queries could result in the lack of CPU resources for processing the current data ingestion stream.
Prevent this by delaying queries' execution until free resources are available for data ingestion.

Expose `vm_search_delays_total` metric, which may be used in for alerting when there is no enough CPU resources
for data ingestion and/or for executing heavy queries.

app/vmalert: add retries to remotewrite (#605) 
* app/vmalert: add retries to remotewrite

Remotewrite pkg now does limited number of retries if write request failed.
This suppose to make vmalert state persisting more reliable.

New metrics were added to remotewrite in order to track rows/bytes sent/dropped.

defaultFlushInterval was increased from 1s to 5s for sanity reasons.
