Add cellular diagnostics support for Sequans radio modem.

Add additional command about all carrier profiles that are supported.

- the function getNetworkStatus(Json::Value& jData) changed to follow common logic (jDebug is empty when the main status command is failed)
- removed unnecessary prints from the secondary status commands

Implementing CB610L radio modem support

- function getRegistrationCommands() implemented as
pure virtual and overrided for every base radio model
- minor indentation fixes
- function getSimStatusSummary(Json::Value& jData) changed to process
radio modems that do not have separate commands for the SIM presence check
- function getManufacturer(std::string& sManufacturer) changed: AT command changet to 'AT+CGMI'
- src/MTS_IO_QuectelRadio.cpp -- comments correction

- 310650 - Cisco Jasper MVNO in AT&T network - from UBX-13001820 - R13;
- 310890 - Verizon - from UBX-13001820 - R13;
- 311270 - Verizon - from VZ_REQ_LTEB13NAC_12084129, IMS SIM;
- 311480 - Verizon - from VZ_REQ_LTEB13NAC_12084129, IMS SIM;
- 312770 - Verizon - from the output of AT#FWPLS? on a 5SG1 radio.

Define the set of debugging AT commands and a function to execute such
commands. The function executes the commands one-by-one end returns raw command
outputs. To be used by radio-query --diagnostics.

Executing AT#RFSTS while the SIM card is locked by PIN or PUK causes a deadlock
in the legacy LE910 (LAT1, LEU1, LVW2) firmware. Avoid executing AT#RFSTS if
the SIM card is locked by PUK.
