* Alerting: Don't stop the migration when alert rule tags are invalid
As we migrate we expect the `alertRuleTags` on a dashboard alert to be a JSON object. However, it seems this is not really validated by Grafana and an user can change the format to something else that the JSON parser is not able to marshal into a `map[string]string`.
Let's do a bit better by "attempting" to parse the tags and if we can't we'll simple return an empty map. The data is still there so if the user wishes they can go back, fix the data and attemp the migration again.
Migrations:
* add a new column alert_group_idx to alert_rule table
* add a new column alert_group_idx to alert_rule_version table
* re-index existing rules during migration
API:
* set group index on update. Use the natural order of items in the array as group index
* sort rules in the group on GET
* update the version of all rules of all affected groups. This will make optimistic lock work in the case of multiple concurrent request touching the same groups.
UI:
* update UI to keep the order of alerts in a group
* Alerting: Add first Grafana reserved label g_label
g_label holds the title of the folder container the alert. The intention of this label
is to use it as part of the new default notification policy groupBy.
* Add nil check on updateRule labels map
* Disable gocyclo lint on schedule.ruleRoutine
will remove later in a separate refactoring PR to reduce complexity.
* Address doc suggestions
* Update g_folder for rules in folder when folder title changes
* Remove global bus in FolderService
* Modify tests to fit new common g_folder label
* Add changelog entry
* Fix merge conflicts
* Switch GrafanaReservedLabelPrefix from `g_` to `grafana_`
* optional custom description for OpsGenie
* custom title and message, tests
* update changelog
* check for empty / whitespace only strings
* truncate the title to 130 characters if needed
* unnecessary validation removed
* truncate title to 127 characters and add three dots
* Alerting: decapitalize log lines and use "err" as the key for errors
Found using (logger|log).(Warn|Debug|Info|Error)\([A-Z] and (logger|log).(Warn|Debug|Info|Error)\(.+"error"
* Alerting: Remove double quotes from matchers
With #38629 a new Alertmanager configuration object was introduced with `object_matchers`, it was meant to circumvent around the fact that Prometheus label names don't support a set of characters that Grafana needs to support for alerts, silences, matchers, etc. (with a common example being elasticsearch's `.`).
This new object does not include the label of sanitzation or validation that its Prometheus equivalent supports in `matchers` and therefore are semantically not equivalent.
This triggered the problem that when the migration is run, we use `matchers` as the object to populate in configuration for routing policies, but when the UI does its first save this object is transformed to `object_matchers`.
Matchers that were previously running just fine would immediately stop working as soon as the configuration is saved.
This problem surfaced with the introduction of #49952 where we stopped stripping double quotes from matchers (not just regex but _all_ of them).

* introduce a fallback handler that checks that role is Viewer.
* update UI nav links to allow alerting tabs for anonymous user
* update rule api to check for Viewer role instead of SignedIn when RBAC is disabled
* Alerting: Create fewer contact points on migration
Previously a new contact point was created for every unique combination
of channels attached to any legacy alert. This was very hard to maintain,
requiring modifications in every generated contact point.
This change deduplicates the generated contact points to a more
reasonable state. There should now only be one contact point per legacy
channel, and we attached multiple contact points to a route by nesting
them. The sole exception to this is if there were multiple default
legacy channels, in which case we create a redundant contact point
containing all of them used only in the root policy. This allows for a
much simpler notification policy structure.

* remove not used code:
- remove offset in ticket because it is not used
- remove unused ticker and scheduler methods
* use duration for interval
* add metrics grafana_alerting_ticker_last_consumed_tick_timestamp_seconds, grafana_alerting_ticker_next_tick_timestamp_seconds, grafana_alerting_ticker_interval_seconds
* Test composition simplification from last PR
* Policies use proper API model everywhere
* Expose policy provenance in API, miss some dep injection
* Complete injection
* fix args
* Tests for provenance value
* Extract test helpers so tests are very readable
* Single source adapter struct that was copied in 3 places
* Drop redundant test
* Resolve merge conflicts on changelog
Before this change, notifications generated by the Grafana Alertmanager
pointed to '/alerting/:ruleID/edit'. This change instead points them to
the view path '/alerting/grafana/:ruleID/view'. The view page has a
better UX, including timeseries display. It's also where many alert
state improvements will land in the next few versions of Grafana.
