fixed applying remoteWrite.label for pushed metrics (#4247) (#4824)
vmagent: properly add extra labels before sending data to remote storage

labels from `remoteWrite.label` are now added to sent metrics just before they
 are pushed to `remoteWrite.url` after all relabelings, including stream aggregation relabelings (#4247)
