Instead of using the command module for retrieving a sysctl value then
we can use the slurp module and read the value directly from /proc.

[1] introduced a regression on the fs.aio-max-nr sysctl value condition.
The enable key isn't a boolean but a string because the expression isn't
evaluated.
This string output "(osd_objectstore == 'bluestore')" is always true
because item.enable condition only matches non empty string. So the
sysctl value was applyied for both filestore and bluestore backend.
[2] added the bool filter to the condition but the filter always returns
false on string and the sysctl wasn't applyed at all.
This commit fixes the enable key value by evaluating the value instead
of using the string.

By running ceph-ansible there are a lot ``[DEPRECATION WARNING]`` like these:
```
[DEPRECATION WARNING]: evaluating containerized_deployment as a bare variable,
this behaviour will go away and you might need to add |bool to the expression
in the future. Also see CONDITIONAL_BARE_VARS configuration toggle.. This
feature will be removed in version 2.12. Deprecation warnings can be disabled
by setting deprecation_warnings=False in ansible.cfg.
```
Now appended ``| bool`` on a lot of the affected variables.
Sometimes the coding style from ``variable|bool`` changed to ``variable | bool`` *(with spaces at the pipe)*.
Closes: #4022

The order of fs.aio-max-nr (which is hard-coded to 1048576) means that
if you set fs.aio-max-nr in os_tuning_params it will effectively be
ignored for bluestore scenarios.
To resolve this we should move the setting of fs.aio-max-nr above the
setting of os_tuning_params, in this way the operator can define the
value of fs.aio-max-nr to be something other than 1048576 if they want
to.
Additionally, we can make the sysctl settings happen in 1 task rather
than multiple.
