* Stop redacting receivers by default in receiver_svc
[REDACTED] is only used in provisioning API since response doesn't include
SecureFields. This is not necessary in k8s or notifications api, instead we do
not include the encrypted settings in Settings at all, leaving it to
SecureFields to specify when a secure field exists.
* Capitalize logs messages
* Replace global authz abstraction with one compatible with uid scope
* Replace GettableApiReceiver with models.Receiver in receiver_svc
* GrafanaIntegrationConfig -> models.Integration
* Implement Create/Update methods
* Add optimistic concurrency to receiver API
* Add scope to ReceiversRead & ReceiversReadSecrets
migrates existing permissions to include implicit global scope
* Add receiver create, update, delete actions
* Check if receiver is used by rules before delete
* On receiver name change update in routes and notification settings
* Improve errors
* Linting
* Include read permissions are requirements for create/update/delete
* Alias ngalert/models to ngmodels to differentiate from v0alpha1 model
* Ensure integration UIDs are valid, unique, and generated if empty
* Validate integration settings on create/update
* Leverage UidToName to GetReceiver instead of GetReceivers
* Remove some unnecessary uses of simplejson
* alerting.notifications.receiver -> alerting.notifications.receivers
* validator -> provenanceValidator
* Only validate the modified receiver
stops existing invalid receivers from preventing modification of a valid
receiver.
* Improve error in Integration.Encrypt
* Remove scope from alert.notifications.receivers:create
* Add todos for receiver renaming
* Use receiverAC precondition checks in k8s api
* Linting
* Optional optimistic concurrency for delete
* make update-workspace
* More specific auth checks in k8s authorize.go
* Add debug log when delete optimistic concurrency is skipped
* Improve error message on authorizer.DecisionDeny
* Keep error for non-forbidden errutil errors
* Add single receiver method
* Add receiver permissions
* Add single/multi GET endpoints for receivers
* Remove stable tag from time intervals
