Guillaume Abrioux 53793b352e tests: (lvm_setup.yml), don't shrink lvol 
when rerunning lvm_setup.yml on existing cluster with OSDs already
deployed, it fails like following:

```
fatal: [osd0]: FAILED! => changed=false
  msg: Sorry, no shrinking of data-lv2 to 0 permitted.
```

because we are asking `lvol` module to create a volume on an empty VG
with size extents = `100%FREE`.

The default behavior of `lvol` is to shrink the volume if the LV's current
size is greater than the requested size.

Given the requested size is calculated like this:

`size_requested = size_percent * this_vg['free'] / 100`

in our case, it is similar to:

`size_requested = 100 * 0 / 100` which basically means `0`

So the current LV size is well greater than the requested size which
leads the module to attempt to shrink it to 0 which isn't obviously now
allowed.

Adding `shrink: false` to the module calls fixes this issue.

Functional tests

These playbooks aim to individually validate each Ceph component. Some of them require packages to be installed. Ideally you will run these tests from a client machine or from the Ansible server.
