test_power: Add CHARGE_COUNTER properties 



CHARGE_COUNTER is really general in other power supply drivers and
Android also has an interface to monitor CHARGE_COUNTER, so let's
add it into test framework.

Set default as -1000 is because the default status is
POWER_SUPPLY_STATUS_DISCHARGING, which means the counter should be
negative, and 1000 means not zero but small enough.
