the Message classes are shared by OSD and other components of Ceph,
and the throttle in Policy class is different in seastar and
non-seastar world. we will have different implementations for the
seastar applications and non-seastar apps, to consolidate these
two implementations, we need to introduce a common interface for
them.

This commit adds the config options stored by the MON database to the
configuration documentation page.
One can filter for these config options by setting the 'Source' filter
to 'mon' on the configuration documentation page.

Policy implementation takes care of evenly balancing images
across rbd mirror instances. This is done when images are
added to the map and/or instances are added or removed with
the exception of image removal -- removing images does not
reshuffle other (mapped) images which can result in some of
the instances under loaded (in worst case, if one removes
images which all map to a particular instance, that instance
would remain idle until more images are added or a shuffle is
triggered).
We could possibly trigger map shuffle when images are removed,
but that would change the interface between Policy and ImageMap
class (in the form of changes to Policy::remove_images()). Also,
policy (and its implementations) would have to do more work when
the above class method is invoked.
Therefore, an interval based rebalancer is added to ImageMap for
periodic rebalancing of images only if the following conditions
are met:
- policy has been idle for a configured time duration
- no scheduled or in-transit operations

The final state transition when disassociating (removing) images
does not purge the image state map for a given image. This can
also result in uneven balance of images across instances as the
policy implementation relies on this structure to figure out
total number of images tracked.

and templaterize it. as we need to share Policy between seastar app and
non-seastar apps. and the Throttle interface for seastar is different
from that for non-seastar, so we should templaterize the Policy and
PolicySet.

This patch is about:
- Adding the missing headers from src/messages
- Adding the missing types from the existing headers
- Adding blank lines to keep includes and types in a visual block.
That is much easier to read and keep the same visual as the rest of the file.

The problem was that object[] weren't handled in the key value table
before. Now they will be stringified to prevent an output like
