Sean Dague 0fcec69a23 deprecate manager class options
We should deprecate the manager classes used for all of our
services. This is not a thing we actually expect or want to support
people replacing. If we want modular plug points at any of these all
the options should be in tree and specified by constants to switch
between.

deprecations:
- Nove used to support the concept that ``service managers`` were
replaceable components. There are many config options where you can
replace a manager by specifying a new class. This concept is
deprecated in Mitaka as are the following config options.
* [cells] manager
* metadata_manager
* compute_manager
* console_manager
* consoleauth_manager
* cert_manager
* scheduler_manager
Many of these will be removed in Newton. Users of these options
are encouraged to work with Nova upstream on any features missing
in the default implementations that are needed.
