Set of arrangements to fix ssl problems

* splitted ssl cert installation and trusting it as we will have to trust the
  certificate on all nodes which need to call any openstack apis
* Just put trust_selfsigned_cert code in rjil::base, it is not required to
  trust the cert on some set of servers like st nodes, etcd , but st node is not
  there in virtual node scenario and etcd is the only one left, so I put it as
  part of rjil::base, it may be changed as and when required.
* Changed some consul service definition to handle http calls with ssl
* Included port for radosgw tests as including ssl change the default port to
  443
* Fixed spec tests
