Objecter: resend linger ops on any interval change

Objecter: resend linger ops on any interval change

Watch/notify ops need to be resent after a pg split occurs, as well as
a few other circumstances that the existing objecter checks did not
catch.

Refactor the check the OSD uses for this to add a version taking the
more basic types instead of the whole OSD map, and stash the needed
info when an op is sent.
