cluster: adds /api/v1/update/series API 
It allows to modify exist series values.
User must write modified series into vminsert API
/insert/0/prometheus/api/v1/update/series

vminsert will generate id and add it to the series as __generation_id
label.

Modified series merged at vmselect side.
Only last series modify request at given time range will be applied.
Modification request could be exported with the following API request:
`curl localhost:8481/select/0/prometheus/api/v1/export -g -d
'reduce_mem_usage=true' -d 'match[]={__generation_id!=""}'`

README.md

vmselect performs the following tasks:

  • Splits incoming selects to tasks for vmstorage nodes and issues these tasks to all the vmstorage nodes in the cluster.

  • Merges responses from all the vmstorage nodes and returns a single response.

The vmui directory contains static contents built from app/vmui package with make vmui-update command. The vmui page is available at http://<vmselect>:8481/select/<accountID>/vmui/.
