Updates vagrant README

The vagrant-devstack-Kuryr-Kubernetes 'Vagrant Options available' in
the README stated that the default VAGRANT_KURYR_VM_MEMORY is 4096,
this change updates it to 6144. And mentions that for a lighter
devstack installation ovn and ovn-octavia driver can be used.
This change also updates the url for atlas.

It will take from 10 to 60 minutes, depending on your internet speed.

5. `vagrant ssh`
At this point you should have experimental kubernetes (etcdv3, k8s-apiserver,
k8s-controller-manager, k8s-scheduler, kubelet and kuryr-controller), docker,
kuryr, neutron, keystone all up, running and pointing to each other. Pods and
services orchestrated by kubernetes will be backed by kuryr+neutron. The
architecture of the setup can be seen at [1].

Vagrant Options available
-------------------------
@ -34,23 +34,28 @@ You can set the following environment variables before running `vagrant up` to m
the definition of the Virtual Machine spawned:
* **VAGRANT\_KURYR\_VM\_BOX**: To change the Vagrant Box used. Should be available in
[atlas](http://atlas.hashicorp.com).
[atlas](https://app.vagrantup.com/).
export VAGRANT_KURYR_VM_BOX=centos/7
Could be an example of a rpm-based option.
* **VAGRANT\_KURYR\_VM\_MEMORY**: To modify the RAM of the VM. Defaulted to: 4096
If you configure your local.conf to use Octavia, you should increase the
setting to at least 12288.
* **VAGRANT\_KURYR\_VM\_MEMORY**: To modify the RAM of the VM. Defaulted to: 6144.
If you mean to create multiple Kubernetes services on the setup and the Octavia
driver used is Amphora, you should increase this setting.
* **VAGRANT\_KURYR\_VM\_CPU**: To modify the cpus of the VM. Defaulted to: 2.
If you configure your local.conf to use Octavia, you should increate this
setting to at least 4.
* **VAGRANT\_KURYR\_RUN\_DEVSTACK**: Whether `vagrant up` should run devstack to
have an environment ready to use. Set it to 'false' if you want to edit
`local.conf` before run ./stack.sh manually in the VM. Defaulted to: true.
See below for additional options for editing local.conf.
For a lighter devstack installation, you can use the "local.conf"[1] that uses ovn
and ovn-octavia, no VM will be created for each load-balancer as is done by the
default Octavia provider (Amphora).
