This adds ceph_crush_rule ansible module for replacing the command
module usage with the ceph osd crush rule commands.
This module can manage both erasure and replicated crush rules.

When `rule_name` isn't set in `crush_rules` the osd pool creation will
fail.
This commit adds a new fact `ceph_osd_pool_default_crush_rule_name` with
the default crush rule name.

Creating crush rules even with no crush hierarchy configuration is a
valid scenario so we shouldn't be bound to the first task result (which
configure crush hierarchy) to be able to add new crush rules.

Since ed36a11 we move the crush rules creation code from the ceph-mon to
the ceph-osd role.
To keep the backward compatibility we kept the possibility to set the
crush variables on the mons side but we didn't move the default values.
As a result, when using crush_rule_config set to true and wanted to use
the default values for crush_rules then the crush rule ansible task
creation will fail.
"msg": "'ansible.vars.hostvars.HostVarsVars object' has no attribute
'crush_rules'"
This patch move the default crush variables from ceph-mon to ceph-osd
role but also use those default values when nothing is defined on the
mons side.

This adds device class support to crush rules when using the class key
in the rule dict via the create-replicated sub command.
If the class key isn't specified then we use the create-simple sub
command for backward compatibility.

If we want to create crush rules with the create-replicated sub command
and device class then we need to have the OSD created before the crush
rules otherwise the device classes won't exist.
