CLOUDSTACK-6975: Prevent dnsmasq from starting on backup redundant RvRRebase of PR #1509 against the 4.7 branch as requested by @swill One LGTM from @ustcweizhou carried from previous PR. Previous PR will be closed. Description from PR #1509: CLOUDSTACK-6975 refers to service monitoring bringing up dnsmasq but this is no-longer accurate, as service monitoring is not active on the post-4.6 routers. These routers still suffer an essentially identical issue, however, because "dnsmasq needs to be restarted each time configure.py is called in order to avoid lease problems." As such, dnsmasq is still running on backup RvRs, causing the issues described in CLOUDSTACK-6975. This PR is based on a patch submitted by @ustcweizhou. The code now checks the redundant state of the router before restarting dnsmasq. RvR networks without this patch have dnsmasq running on both master and backup routers. RvR networks with this patch have dnsmasq running on only the master router. * pr/1514: CLOUDSTACK-6975: Prevent dnsmasq from starting on backup redundant RvR.
