It's now possible to register SMA device managers defined in a module
outside of the regular directory. To do that, a global variable called
`devices` containing a list of device manager classes needs to be defined
in a module that's added to SMA_PLUGINS environment variable.
For example:
```
$ cat /path/to/plugins/external_devices/__init__.py
import spdk.sma as sma
class MyDeviceManager1(sma.DeviceManager):
pass
class MyDeviceManager2(sma.DeviceManager):
pass
devices = [MyDeviceManager1, MyDeviceManager2]
$ SMA_PLUGINS=external_devices scripts/sma.py
```
Multiple plugins can be specified by separating them with a colon, e.g.:
```
SMA_PLUGINS=plugin1:plugin2
```
Of course, the location at which these modules reside must be in
PYTHONPATH.
