Reduce deadletters (RTL-3780)

SyncSubscriptionJob correctly handles executions lasting more than 30s but no longer than 2min, which should reduce number of deadletters due to lost locks on service bus events.

Create audit fields are overwritten for existing data (RTL-4059)

Data synchronization between Retail and Loyalty database by LpMemberMerger job does not updated CreatedBy and CreatedDate audit fields. Welcome emails are not triggered for existing members.

Add support for Multiple Loyalty Programs (RTL-3981)

StampCard service distincts, which members belong to which loyalty program and for 'all members' campaigns type, the service triggers empty stamp cards for members who belong to the loyalty program of created StampCard Campaign.

That means from now on empty standards are created automatically for all members and there is no need to trigger them using POS.
