As ScrubResources is no longer involved in remote reservations, some
of the data listed by 'dump_scrub_reservations' is now collected by
OsdScrub itself (prior to this change, OsdScrub just forwarded the
request to ScrubResources).

If the score did not improve, we should clear out any
pending pg-upmap-primary mappings so they don't execute
in situations where the same incremental is used to balance
multiple pools (i.e. in the balancer mgr module).

Followup to 8a5553597c.
Streamlines some of the logic so pg upmap activity is properly
initalized, and updated in offline mode as well as online.

Read balancing may now be managed automatically via the balancer
manager module. Users may choose between two new modes: ``upmap-read``, which
offers upmap and read optimization simultaneously, or ``read``, which may be used
to only optimize reads. Existing balancer commands have also been added to
contain more information about read balancing.
Run the following commands to test the new automatic behavior:
`ceph balancer on` (on by default)
`ceph balancer mode <read|upmap-read>`
`ceph balancer status`
Run the following commands to test the new supervised behavior:
`ceph balancer off`
`ceph balancer mode <read|upmap-read>`
`ceph balancer eval` | `ceph balancer eval <pool-name>`
`ceph balancer eval-verbose` | `ceph balancer eval-verbose <pool-name>`
`ceph balancer optimize <plan-name>`
`ceph balancer show <plan-name>`
`ceph balancer eval <plan-name>`
`ceph balancer execute <plan-name>`
In the balancer module, there is also a new "self_test" function which tests
the module's basic functionality. This test can be triggered with the following
commands:
`ceph mgr module enable selftest`
`ceph mgr self-test module balancer`

The scrub async reserver is not yet used. All requests are treated as
'legacy' requests, i.e. requests that expect an immediate grant/deny
reply.

Up-to-date primaries will set this flag when sending a reservation
request. The replica OSD, if too busy to handle the request immediately, will queue
it until such time that the number of concurrent reservations is below the
configured limit. The queued requests are honored in FIFO order.
Old primaries will not set this flag, and will receive the expected
grant or deny reply immediately.

CloudFlare engineers made some testing and realized that using
workqueues with encryption on flash devices has a bad effect.
See [1] for details.
With this patch it will make ceph-volume call crypsetup with
`--perf-no_read_workqueue` and `--perf-no_write_workqueue` options
when the device is not a rotational.

Mapping rbd images to nbd devices using ioctl interface is not
robust. It was discovered that the device size or the md5 checksum
of the nbd device was incorrect immediately after mapping using
ioctl method. When using the nbd netlink interface to map RBD images
the issue was not encountered. Switch to using nbd netlink interface
for mapping.
