This patch utilize generic sma implementation by adding vhost-user
devices manager. It's allow to expose virtualized block devices to
QEMU instances or other arbitrary processes.
Max device capacity depend on available `pci-bridge`
```
devices:
- name: 'vhost_blk'
params:
buses:
- name: 'pci.spdk.0'
count: 32
- name: 'pci.spdk.1'
count: 32
qmp_addr: 127.0.0.1
qmp_port: 9090
```
To attach `pci-bridge` at boot time we need to run qemu with this option
```
device pci-bridge,chassis_nr=1,id=pci.spdk.0
device pci-bridge,chassis_nr=2,id=pci.spdk.1
