Alerting: v0 schema for integrations (mimir) (#110908)

* generate schema for mimir integrations from schema on front-end
* review and fix the settings
* Update GetAvailableNotifiersV2 to return mimir as v0
* add version argument to GetSecretKeysForContactPointType
* update TestGetSecretKeysForContactPointType to include v0
* add type alias field to contain alternate types that different from Grafana's
* add support for msteamsv2
* update ConfigForIntegrationType to look for alternate type
* update IntegrationConfigFromType to use new result of ConfigForIntegrationType
* add reference to parent plugin to NotifierPluginVersion to allow getting plugin type by it's alias
* add tests to ensure consistency
* make API response stable
* add tests against snapshot + omit optional fields
