High power consumption on simple GPIO interrupt application

Please see known issue NCSDK-10106. When running applications that do not enable Modem library on nRF9160 with build code B1A, current consumption will stay at 3 mA when in sleep. Try to init your modem so that it will have the correct sleep current

Change interrupt type from edge to level, either active high or active low, and you will see a significant drop in current. This seems to be an issue with GPIO interrupt APIs when using edge-triggered interrupts. In my case, using level-triggered interrupts instead of edge-triggered ones significantly reduced the current.

ret = gpio_pin_interrupt_configure(pulse.port,pulse.pin,GPIO_INT_LEVEL_LOW);
