bdev/nvme: Aggregate multiple ctrlrs into a single bdev ctrlr

Browse Source 
This patch enables us to aggrete multiple ctrlrs in the same NVM
subsystem into a single bdev ctrlr to create multipath.

This patch has a critical limitation that ctrlrs which are aggregated
need to have no namespace. Hence any nvme bdev is not created.
However it will be removed in the next patch.

The design is as follows.

A nvme_bdev_ctrlr is created to aggregate multiple nvme_ctrlrs in
the same NVM subsystem. The name of the nvme_ctrlr is changed to be
the name of the nvme_bdev_ctrlr.

NVMe bdev module has both the failover feature and the multipath
feature now. To choose which of failover or multipath to use, add an new
parameter multipath to the RPC bdev_nvme_attach_controller.

When we attach a new trid to the existing nvme_bdev_ctrlr, we use the failover
feature if multipath is false, we use the multipath feature if multipath is
false.

nvme_bdev_ctrlr has a list for nvme_ctrlr and it is guarded by the
global mutex. Callers can query nvme_ctrlrs from a nvme_bdev_ctrlr via
trid as a key. nvme_bdev_ctrlr is not registered as io_device.
