Too much logging when deserialization error occurred

[alkampfergit]

If a commit cannot be deserialized, Polling starts sending a high amount of Errors in the log, in the meanwhile the user of the poller has no clue that something wrong is happened and the poller is stuck.

We need

• [ ] Logging each X minutes, it has no sense to log an exception for each polling tentative
• [ ] Creating a property in the poller that states that the poller is in Error state. This will allow consumer program to react or setting some alert.

Here is text of exception

Error during polling client System.FormatException: An error occurred while deserializing the Body property of class NEventStore.EventMessage: Element 'XXXXXXX' does not match any field or property of class DMS.Shared.Model.Container.Events.ContainerCreated. ---> System.FormatException: Element 'XXXXXXX' does not match any field or property of class DMS.Shared.Model.Container.Events.ContainerCreated.

This is an issue of CommitPollingClient2, so the issue was moved to the core framework.
