If a class is no more referenced by any devices or crush rules,
it shall be considered as dead.
This patch makes Ceph automatically recycles those dead classes,
so user does not to explicitly call 'class rm', which is unsafe
and annoying.

The current version is broken. E.g., it should only remove a class
which is never referenced by any device.
Since we now create new classes automatically, we shall automatically
recycle dead classes too. So this command is definitely unuseful.
(Actually it is weird that we keep 'class rm' without keeping the
corresponding 'class create' command).

As per coding Guidelines 'const int' is recommended over 'int const'
https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md
NL.26: Use conventional const notation
Example:
const int x = 7; // OK
int const y = 9; // bad
Note
We are well aware that you could claim the "bad" examples more logical than the ones marked "OK", but they also confuse more people, especially novices relying on teaching material using the far more common, conventional OK style.
As ever, remember that the aim of these naming and layout rules is consistency and that aesthetics vary immensely.
Enforcement
Flag const used as a suffix for a type.

Additionally makes sure when unexpected values are provided for config
options osd_op_queue or osd_op_queue_cut_off that the default values
are assigned.
