Now `vminsert` accepts AccountID and ProjectID via `VictoriaMetrics_AccountID` and `VictoriaMetrics_ProjectID` tags
when reading Influx line protocol data via plain TCP or UDP (i.e. when `-influxListenAddr` is set).

0157566fdb vmalert: cleanup and restructure of code to improve maintainability (#471) 
The change introduces new entity `manager` which replaces
`watchdog`, decouples requestHandler and groups. Manager
supposed to control life cycle of groups, rules and
config reloads.

Groups export an ID method which returns a hash
from filename and group name. ID supposed to be unique
identifier across all loaded groups.

Some tests were added to improve coverage.

Bug with wrong annotation value if $value is used in
 templates after metrics being restored fixed.

Notifier interface was extended to accept context.

New set of metrics was introduced for config reload.

3052b479b7 lib/httpserver: reduce typical duration for http server graceful shutdown 
Previously the duration for graceful shutdown for http server could take more than a minute
because of imporperly set timeouts in setNetworkTimeout.
Now typical duration for graceful shutdown should be reduced to less than 5 seconds.

plus a code that isn't used by VictoriaMetrics. So let's use a private copy under our control instead.

989d84cf3f app/{vminsert,vmstorage}: wait for ack from vmstorage after each packet sent to it from vminsert 
This should protect from possible data loss when `vmstorage` is stopped while the packet is sent from `vminsert`.

This commit switches to new protocol between vminsert and vmstorage, which is incompatible
with the previous protocol. So it is required that both vminsert and vmstorage nodes are updated.

e933cbac16 lib/storage: postpone reading data from blocks during search 
This eliminates the need for storing block data into temporary files on a single-node VictoriaMetrics
during heavy queries, which touch big number of time series over long time ranges.

This improves single-node VM performance on heavy queries by up to 2x.
