    Add retry support to pecan
    
    This modifies the expose and when decorators in
    pecan to also include the olso db API retry logic
    so all controllers that leverage these automatically
    get the retry logic to handle temporary DB errors.
    
    To accomplish this, the ATTR_NOT_SPECIFIED sentinel
    was modified to be friendly to copy.deepcopy since
    unlike in the old API, the new logic will be sending
    copies to the core plugin after the attributes have
    been populated.
    
    This also includes a workaround for a bad assumption
    in the pecan decorator utils that assumes all decorators
    have a __code__ attribute.
