move features flags into queue_limits

[Christoph Hellwig]

Hi all,

this is the third and last major series to convert settings to
queue_limits for this merge window.  After a bunch of prep patches to
get various drivers in shape, it moves all the queue_flags that specify
driver controlled features into the queue limits so that they can be
set atomically and are separated from the blk-mq internal flags.

Note that I've only Cc'ed the maintainers for drivers with non-mechanical
changes as the Cc list is already huge.

This series sits on top of the "convert the SCSI ULDs to the atomic queue
limits API v2" and "move integrity settings to queue_limits v2" series.
