Mark some Summaries explicitly as having no objectives 

With the next release of client_golang, Summaries will not have
objectives by default. Interestingly, this will do the right thing for
the Summaries affected by this commit. However, right now those
summaries do get the old default objectives. They don't really make
sense because the affected Summaries receive Observations quite
infrequently (far less than once in the 10m max age currently
used). To not get surprising changes when moving on to client_golang
v1, let's explicitly set the Summaries as objective-less now.
