rgw: simplify RGWUserCtl params with default arguments

Params types needed to define a non-default constructor as a workaround

rgw: make optional_yield explicit in RGWUserCtl interfaces

the purpose of null_yield is to highlight synchronous function calls so
they can be found with grep. having optional_yield parameters or member
variables that default to null_yield obscures these synchronous calls,
so optional_yield arguments should be an explicit part of interfaces

moved optional_yield out of RGWUserCtl's various Param types, and
updated all callers to pass in null_yield (except for a few cases where
the caller had access to a valid one)

rgw: initial meta manager refactoring

I didn't intend for it to be such a big commit, and it's not
even compiling yet. This changes the structure of how
the metadata manager and handlers work.
The idea is to be able to relatively easily hook in different
meta backends (or same backends with different handling -- such
as the otp).
Added new services for meta, meta backend, and meta backend sysobj
implementation.
The meta backend service is responsible for the final data storage,
and updating the meta log (log might be split later on, but at the
moment it keeping it together for simplicity).
The handlers themselves are the ones responsible for reading or
modifying the metadata. This means that they need to call the
meta backend service instead of calling the utility functions.
The utility functions need to call the handlers, and not the other
way around. Handlers can have utility methods to assist.

Left to do: get everything actually compiling and implemented. The
structure is there, now need to fill in the gaps.
