Add automatic (un)installation steps for RPM-based install
RPM spec: Don't depend on BIRD, as BIRD isn't available in RPM form for RHEL 6.5
Install config files under /etc, not /usr/etc
Enable calico-compute service in the usual runlevels
Use iptables -D on RHEL 6.5 instead of iptables -C, for avoiding duplicate DHCP checksum rules
Depend on openstack-neutron-linuxbridge, for "from neutron.plugins.linuxbridge.common import config"
Don't assume that /etc/bird already exists when generating BIRD config
Enhance how we (re)start BIRD to work for RHEL as well as for Ubuntu
Don't reject INPUT and FORWARD packets by default on the compute host
