Removed CellularBase and AT_CellularBase from cellular stack and updated both code and unittests accordingly.
Moved property handling into AT_CellularDevice
A new API `CellularDevice::clear()` to clean-up the modem to a default initial state.
Function is virtual so it can be overridden. The default implementation clears all PDP contexts,
but the the first one if that has APN defined as `nsapi.default-cellular-apn`.
CellularStateMachine calls `clear()` to clean-up the modem on initial `connect()`,
if the flag `cellular.clear-on-connect: true` is defined.
Disconnect was sent to all CellularContext classes even it concerned
one specific context. Some disconnect events are still sent to all
context classes. These event are coming from network and ment for all
context classes or event did not specify cid.
This was left accidentally after refactoring.
It wasn't giving correct states after refactoring.
CellularContext::get_connection_status should be used instead.
-added an API for checking network eps ciot optimization support
-renamed the API for getting the UE parameters
-the API for setting the UE parameters includes now a callback, which
will be called once network support for eps ciot optimization is known
