        cpd: to correct failover behavior of cpsv [#1765]

        problem: In case a failover happens while a checkpoint is being 
unlinked, it
        might causes an unfinished unlink operation (i.e the checkpoint IMM 
        is not deleted). Later on, when the checkpoint is created again, it 
will not
        succeed because the CPD detects that the checkpoint IMM object existing.

        - When error occur delete the existing checkpoint IMM object and 
re-create new
        - Stop timer of removed node.
        - Update data in patricia trees.

___ You need to refactor your submission into logical chunks; there is
    too much content into a single commit.

___ You have extraneous garbage in your review (merge commits etc)

___ You have giant attachments which should never have been sent;
    Instead you should place your content in a public tree to be pulled.

___ You have too many commits attached to an e-mail; resend as threaded

___ You have resent this content multiple times without a clear indication
    of what has changed between each re-send.
