constantly relookup ip for etcd host

to ensure that you don't wind up in a race
condition that I have seen where the lookup
call returns the private address b/c the
public one is not assigned yet.

this will continuously re-lookup the address
until the specified command works.
Use default for contrail_api_server

Default is provided by consul and just works
Use proxy
Add clockskew debug to crontab
I hate computers
Make sure we run ntpdate after configuring ntp but before installing Ceph
Only run ntpdate if ntpd isn't running

...and make sure it runs before installing ntpd so that it actually will
run.

Added consul service for memcache.

* Memcache should be a central service in order to use it to store tokens and to
  use multiple consoleauths. So adding a consul service for that.
* added better test for memcached.
* Added spec tests
Added memcache caching for nova controllers.

This is required for multiple nova consoleauth nodes.
Fixed issue on configuring private_address on cp nodes

There is a problem on configuring private/public address/interface specifically
on compute nodes from hiera data, as during the deployment, the address of
physical interface will be assigned to vhost0.

Added a function to get various details of first interface which has any IP
assigned out of a provided list, or from interfaces fact. Used this function to
assign vncserver_proxyclient_address to make novnc work.
Fail/Errorout the execution on runtime

fail function was used to fail if memcached service was not registered with
  consul. But the problem there was, the memcached was started on the same nodes
  as nova controllers which caused a situation where puppet never executed as fail
  function run on compile time and it did not get a chance to setup memcached.

Added a type to error the puppet execution and thus any dependant resource to
 that wont be running.

Added runtime_fail type to nova controller and made a dependancy to nova_config where
memcache is configured.
Included ntp to avoid spec test failures

Added new role gcp to support contrail vgw

Contrail simple gateway (vgw) is used to provide external network connectivity
without any physical router, in test and development environments.

so gcp1 will be act as an edge router for virtual cloud/vagrant environment.

Since vgw cannot advertise its routes to any other system, one have to add route
manually to reach floating IPs.

In order to access default floating IP pool (100.1.0.0/24) from the machine in
side cloud network (say haproxy1), one have to add below route in it.

route add -net 100.1.0.0/24  gw 10.0.0.10 dev eth0

where 10.0.0.10 is gcp1 IP address, eth0 is the machine's interface by which it
connect to the gw, 100.1.0.0/24 is the floating IP network.

I am working on developing rjil::tempest, in which the code to add appropriate
route on tempest machine will be added as it is required for tempest to pass
floating IP tests.

Added validation checks.

Note:

* There is a race condition between floating IP pool and vgw
 creation. Created a consul kv after creating floating ip pool and blocked vgw
 creation util that kv available.

SPEC tests to be added - I faced an issue on spectest for which I would need
help from Dan.
Add vgw tests only on gcp1 where vgw getting created.
