Add Events to Correspondence

[Andreass2]

Add events to correspondence. A lot of the configuration can be copied from broker. We should probalby wait until we have configuration of service owner and resourceId before doing this.

The following events should happen:

• AttachmentInitialized (Sender)

• AttachmentUploadProcessing (Sender)

• AttachmentPublished (Sender)

• AttachmentPurged (Sender)

• AttachmentFailed (Sender)

• CorrespondenceInitialized (Sender)

• CorrespondenceUploaded (Sender)

• CorrespondencePurged (Sender)

• CorrespondenceArchived (Sender/Receiver)

• CorrespondencePublished (Sender(Receiver)

• CorrespondenceFailed (Sender)

• CorrespondenceReceiverReserved (Sender)

• CorrespondenceReceiverReplied (Sender)

• CorrespondenceReceiverConfirmed (Sender/Receiver)

• CorrespondenceReceiverRead (Sender)

• CorrespondenceNeverConfirmed (Sender/Receiver)

As a correspondence has a VisibleFrom, how/when should we send the event to the receiver? Suggersiton:

• Hangfire background job.

Created #94 to enable events to send the events to Altinn Events instead of Console log event bus.
