1. Added property SampledValue, which will reflect the gpio
value status always, will be used when ignore property is true
2. Removed enabled property, as it is not used anymore
3. Fixed bug for Value property which had the inversion first
before comparison.
Tested:
1. Verified the behavior using D-Bus commands
2. Verified Power-up / Gpio Sampling / etc, along with
Buttons & set-passthrough patch.

Simplified Gpio daemon service and it's corresponding
members. Buttons must use these gpio daemon instead of
directly queriying gpio. Daemon will send out properties
changed signal, when there is change in gpio value.
Introduced Ignore property, if set true will return
cached values for the specified gpio.
Gpio daemon will query objects from entity manager and
initialize accordignly. Restarting gpio daemon, will
re-init these pins as per the entity manager.
Tested:
1. Verified the properties of Power button & Reset button
2. Performed FP buttons operation and made sure power button &
reset button properties changed signals are properly sent out
3. Testd against updated buttons code (which uses gpio daemon)
and verified basic power operations both from front panel and
from ipmitool power
4. Verified object creation, during gpio daemon restart
and also on entity-manager restart

Only gpio with direction set as "input" are monitored. Each gpio by
separate GpioState class. Presently only gpio "value" property is
monitored by looking into file descriptor of /sys/class/gpio/gpioXX/edge.
Planning to be changed into gpio cheracter device soon.

Gpiodaemon handling all gpio related signals
(having "xyz.openbmc_project.Configuration.Gpio" interface)
from Entity Manager to update own gpio configuration.

Service name is "xyz.openbmc_project.Gpio" with below properties:
.Direction
.Enabled
.Value
Whenever "Enabled" is set to "false" the "Value" and "Direction"
properties cannot be overridden.
