[tor/maint-0.3.2] sr: Don't use a dynamic voting schedule

commit 7ee0a2b9aa71693a09687dca431cc1880774f4f4 Author: David Goulet <dgoulet(a)torproject.org> Date: Fri Oct 27 09:16:29 2017 -0400 sr: Don't use a dynamic voting schedule The exposed get_voting_schedule() allocates and return a new object everytime it is called leading to an awful lot of memory allocation when getting the start time of the current round which is done for each node in the consensus.
