ec6ed467c6 app/vmalert: support external.label to specify global labelset for all rules #622 (#652)
`external.label` flag supposed to help to distinguish alert or recording rules
source in situations when more than one `vmalert` runs for the same datasource
or AlertManager.

9afd19d375 app/vmalert: add retries to remotewrite (#605)
* app/vmalert: add retries to remotewrite

Remotewrite pkg now does limited number of retries if write request failed.
This suppose to make vmalert state persisting more reliable.

New metrics were added to remotewrite in order to track rows/bytes sent/dropped.

defaultFlushInterval was increased from 1s to 5s for sanity reasons.

156c83d112 app/vmalert: support multiple notifier urls (#584) (#590)
* app/vmalert: support multiple notifier urls (#584)

User now can set multiple notifier URLs in the same fashion
as for other vmutils (e.g. vmagent). The same is correct for
TLS setting for every configured URL. Alerts sending is done
in sequential way for respecting the specified URLs order.

* app/vmalert: add basicAuth support for notifier client (#585)

The change adds possibility to set basicAuth creds for notifier
client in the same fasion as for remote write/read and datasource.

The change adds no new functionality and aims to move flags definitions
to subpackages that are using them. This should improve readability
of the main function.

app/vmalert: add support for TLS configuration

Add support for TLS optional configuration in a similar fashion to what
is currently supported in other vmutils such as vmagent. TLS
configuration options are distinct for datasource, remoteRead,
remoteWrite as well as notifier.

app/vmalert: Support custom URL for alerts source

Add flag `external.alert.source` for configuring custom URL
for alert's source. This may be handy to re-point default source
URL to other systems like Grafana.

1a01fe2cf2 vmalert-537: allow name duplication for rules within one group. (#559)
Uniqueness of rule is now defined by combination of its name, expression and
labels. The hash of the combination is now used as rule ID and identifies rule within the group.

Set of rules from coreos/kube-prometheus was added for testing purposes to
verify compatibility. The check also showed that `vmalert` doesn't support
`query` template function that was mentioned as limitation in README.

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

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.

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.
