The role contains all the handlers for Ceph services. We decided to
leave ceph-defaults role with variables and a few facts only. This is
useful when organizing the site.yml files and also adding the known
variables to infrastructure-playbooks.

For now our best guess is to count the number of devices and multiply
by osds_per_device. Ideally we'd like to run ceph-volume lvm batch
--report and get the number of OSDs that way, but currently we need
a ceph.conf in place already before we can do that. There is a tracker
ticket that would allow os to get around the need for a ceph.conf:

This avoids errors when the osd scenario choosen does not require
setting devices or lvm_volumes. The default values for these are not
set because they exist in the ceph-osd role, not ceph-defaults.

BlueStore's cache is sized conservatively by default, so that it does
not overwhelm under-provisioned servers. The default is 1G for HDD, and
3G for SSD.
To replace the page cache, as much memory as possible should be given to
BlueStore. This is required for good performance. Since ceph-ansible
knows how much memory a host has, it can set
`bluestore cache size = max(total host memory / num OSDs on this host * safety
factor, 1G)`
Due to fragmentation and other memory use not included in bluestore's
cache, a safety factor of 0.5 for dedicated nodes and 0.2 for
hyperconverged nodes is recommended.

Since the approach to creating a ceph.conf file has changed, and now
no-longer relies on assembling config file fragments in /etc/ceph/ceph.d
we can avoid the conf_overrides rendering on the local host and skip out
the tasks related to that, instead using just the config_template task
to configure the file directly.
This was causing a lot of pain with the handlers. Also the
implementation was not ideal since we were assembling files. Everything
can now be done with the ceph_crush module so let's remove that.

Use a nicer syntax for `local_action` tasks.
We used to have oneliner like this:
```
local_action: wait_for port=22 host={{ hostvars[inventory_hostname]['ansible_default_ipv4']['address'] }} state=started delay=10 timeout=500 }}
```
The usual syntax:
```
local_action:
module: wait_for
port: 22
host: "{{ hostvars[inventory_hostname]['ansible_default_ipv4']['address'] }}"
state: started
delay: 10
timeout: 500
```
is nicer and kind of way to keep consistency regarding the whole
playbook.
This also fix a potential issue about missing quotation :
```
Traceback (most recent call last):

File "/tmp/ansible_wQtWsi/ansible_module_command.py", line 185, in main

raw = self.read_token()
File "/usr/lib64/python2.7/shlex.py", line 172, in read_token
raise ValueError, "No closing quotation"
ValueError: No closing quotation
```
writing `local_action: shell echo {{ fsid }} | tee {{ fetch_directory }}/ceph_cluster_uuid.conf`
can cause trouble because it's complaining with missing quotes, this fix solves this issue.

This allows us to use host-specific variables in ceph_conf_overrides variable. For example, this fixes usage of such variables (e.g. 'nss db path' having {{ ansible_hostname }} inside) in ceph_conf_overrides for rados gateway configuration (see profiles/rgw-keystone-v3) - issue #2157.

The `always_run` key is deprecated and being removed in Ansible 2.4.
Using it causes a warning to be displayed:
[DEPRECATION WARNING]: always_run is deprecated.
This patch changes all instances of `always_run` to use the `always`
tag, which causes the task to run each time the playbook runs.
When Ansible is not run with verbose options it's difficult to see which
include and/or set_fact does what. So adding a name for each clarifies.

The installation process is now described as follow:
* you still have to choose a 'ceph_origin' installation method. The
origin can be a 'repository' (add a new repository), distro (it will use
the packages provided by the native repo source of your distribution),
local (only available on redhat system, it installs locally built
packages). This option is not well tested, so use it carefully
* if ceph_origin == 'repository' you will have to decide what kind of
repository you want to enable:
- community: corresponds to the stable upstream/community version
- enterprise: corresponds to the stable enterprise/downstream version
(basically you are a red hat customer)
- dev: it will install ceph from packages built out of the github
development branches

This will give us more flexibility and the possibility to deploy a client node
for an external ceph-cluster.
