ba1f764b29 lib/fs: optimize queries that read recent samples for big number of time series
Use standard copy() func instead of mmap-aware copy func for reading recently touched mmap-ed data.
This improves read performance by up to 4x.

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* vmalert: rm outdated TODO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

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

exceeds the maximum throughput for connections to vmstorage nodes.

b0131c79b6 lib/storage: improve search speed for time series matching Graphite whildcards such as foo.*.bar.baz
Add index for reverse Graphite-like metric names with dots. Use this index during search for filters
like `__name__=~"foo\\.[^.]*\\.bar\\.baz"` which end with non-empty suffix with dots, i.e. `.bar.baz` in this case.

This change may "hide" historical time series during queries. The workaround is to add `[.]*` to the end of regexp label filter,
i.e. "foo\\.[^.]*\\.bar\\.baz" should be substituted with "foo\\.[^.]*\\.bar\\.baz[.]*".
