[GP-651] LNA7: Allow to start the OMA DM procedure when it is required

This commits adds support for the Quectel-specific OMA DM commands.
This allows to trigger OMA DM procedure om Verizon to fetch the corrent APN
values and other settings from the network.

Expected radio output on success:

```
+QODM: "DME",0,DM Start
+QODM: "DME",0,DM End
```

Other +QODM URC codes are also possible according to information from Quectel forum:
https://forums.quectel.com/t/what-is-the-meaning-of-qodm-fumo-report-failed/2444/5.

But only "DM Start" and "DM End" responses are expected, supported and treated
as correct in the libmts-io.
