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.

vmalert: check if remoteRead object was initied before calling Restore (#473) 
The check for non-nil remoteRead was mistakenly dropped
during refactoring which caused panics when `vmalert`
wasn't configured with `remoteRead` flag.

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.

* app/vmalert: merge with master

86a1cd700b lib/storage: remove inmemory index for recent hour, since it uses too much memory 
Production workload shows that the index requires ~4Kb of RAM per active time series.
This is too much for high number of active time series, so let's delete this index.

Now the queries should fall back to the index for the current day instead of the index
for the recent hour. The query performance for the current day index should be good enough
given the 100M rows/sec scan speed per CPU core.

4c02e496f7 lib/fs: do not postpone directory removal on NFS error 
Continue trying to remove NFS directory on temporary errors for up to a minute.

The previous async removal process breaks in the following case during VictoriaMetrics start

- VictoriaMetrics opens index, finds incomplete merge transactions and starts replaying them.
- The transaction instructs removing old directories for parts, which were already merged into bigger part.
- VictoriaMetrics removes these directories, but their removal is delayed due to NFS errors.
- VictoriaMetrics scans partition directory after all the incomplete merge transactions are finished
  and finds directories, which should be removed, but weren't still removed due to NFS errors.
- VictoriaMetrics panics when it finds unexpected empty directory.

63b05c0b9f app/vmselect/promql: adjust memory limits calculations for incremental aggregate functions 
Incremental aggregate functions don't keep all the selected time series in memory -
they keep only up to GOMAXPROCS time series for incremental aggregations.

Take into account that the number of time series in RAM can be higher if they are split
into many groups with `by (...)` or `without (...)` modifiers.

This should reduce the number of `not enough memory for processing ... data points` false
positive errors.

so it could be monitored and alerted on high error rates.

Export also the counter for processed index blocks with metricIDs - `vm_index_blocks_with_metric_ids_processed_total`,
so its' rate could be compared to `rate(vm_index_blocks_with_metric_ids_incorrect_order_total)`.

from interval between datapoints for each input time series if the flag isn't set.

The interval can be overriden on per-query basis by passing `max_lookback=<duration>` query arg to `/api/v1/query` and `/api/v1/query_range`.
