In case of LTE modem, attaching manually is normally unneeded.
Forcing a detach (in case of gprs-context activation failure) is
actually a mistake, also because this will also trigger a technology
reselection and a possible invalid state, especially for LTE-only
modems.
This simple patch adds a flag to skip the AT+CGATT=x command.
The flag is to be set by vendor-specific options.
By default the behavior remains unchanged.
