e4cef1b678 app/vmstorage: prevent from serving conns from vminsert and vmselect after the server is closed
Previously it was possible that the connection is served after the server is closed if the following
steps are performed:

1) Server accepts new connection.
2) Server.MustClose() is called and successfully finished.
3) Server starts processing the connection accepted at step 1. There could be various crashes
   like in https://github.com/VictoriaMetrics/VictoriaMetrics/issues/534 since the storage may be already closed.

Now the server closes the connection at step 3 without processing it.

44c51c627f vmalert: Add recording rules support. (#519)
* vmalert: Add recording rules support.

Recording rules support required additional service refactoring since
it wasn't planned to support them from the very beginning. The list
of changes is following:
* new entity RecordingRule was added for writing results of MetricsQL
expressions into remote storage;
* interface Rule now unites both recording and alerting rules;
* configuration parser was moved to separate package and now performs
more strict validation;
* new endpoint for listing all groups and rules in json format was added;
* evaluation interval may be set to every particular group;

* vmalert: uncomment tests

* vmalert: rm outdated TODO

* vmalert: fix typos in README

f41a01332a app/vminsert/netstorage: evenly distribute rerouted rows among all the availalbe storage nodes

7a61357b5d app/vminsert/netstorage: make sure that the the data is always replicated among -replicationFactor vmstorage nodes

75f2f3b09d app/vminsert/netstorage: improve ingestion performance when a single vmstorage node is slower than other vmstorage nodes
Previously the ingestion performance has been limited by the slowest vmstorage node.
Now vminsert should re-route data from the slowest vmstorage node to the remaining nodes.

c7f3e58032 vmalert: avoid sending resolves for pending alerts (#498)
Before the change we were sending notifications to notifier
if following conditions are met:
* alert is in Fire state
* alert is in Inactive state

We were sending Inactive notifications to resolve alert ASAP. 
Unfortunately, we were sending resolves for Pending alerts that become
Inactive, which is wrong.

In this change we delete alert from the active list if
it was Pending and become Inactive. In this way we now
have Inactive alerts only if they were in state Fire before.
See test change for example.

e850bf0eff vmalert: fix the access to rules slice element by wrong index (#486)
During group's update rules deletion was causing slice
mutations while slice index was assumed to be unchanged.
This caused "slice bounds out of range" errors when multiple
rules were deleted sequentially.
