* Alerting: Prevent short uid collision in legacy migration when db is case-insensitive
Two factors come into play that cause sporadic uid conflicts during legacy alert migration:
- MySQL and MySQL-compatible backends use case-insensitive collation.
- Our short uid generator is not a uniform RNG and generates uids in such a way that generations in quick succession have a higher probability of creating similar uids.
Normally we would be guaranteed unique short uid generation, however if the source alphabet contains
duplicate characters (for example, if we use case-insensitive comparison) this guarantee is void.
Generating even ~1000 uids in quick succession is nearly guaranteed to create a case-insensitive
duplicate.
* Alerting: Improve notification policies created during migration
Previously, migrated legacy alerts were connected to notification policies through
a `rule_uid` label in a 1:1 fashion. While this correctly mimicked pre-migration routing,
it didn't create a notification policy structure that is easy to view/modify. In addition,
having one policy per migrated alert is, in some ways, counter to the recommended approach of
Unified Alerting.
This change replaces `rule_uid`-based migrated notification policies with a private
label called `__contacts__`. This label stores a list of double quoted strings containing the names of
all contact points an AlertRule should route to (based on legacy notification channels). Finally,
one notification policy is created per contact point with each matching AlertRules via regex on this
`__contacts__` label.
The result is a simpler, clearer, and easier to modify notification policy structure, with the
added benefit that you can see which contact points an AlertRule is being routed to from the
AlertRule creation page.
* 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.

* update AlertingEnabled and UnifiedAlertingSettings.Enabled to be pointers
* add a pseudo migration to fix the AlertingEnabled and UnifiedAlertingSettings.Enabled if the latter is not defined
* update the default configuration file to make default value for both 'enabled' flags be undefined
Misc
* update Migrator to expose DB engine. This is needed for a ualert migration to access the database while the list of migrations is created.
* add more verbose failure when migrations do not match

* Alerting: Validate contact point configuration during the migration
This minimises the chances of generating broken configuration as part of the migration. Originally, we wanted to generate it and not produce a hard stop in Grafana but this strategy has the chance to avoid delivering notifications for our users.
We now think it's better to hard stop the migration and let the user take care of resolving the configuration manually.
