control: Support target_path option in configuration file

The target path containing the interface
xyz.openbmc_project.control.FanPwm or
xyz.openbmc_project.control.FanSpeed can be different between
phosphor-hwmon and dbus-sensor.

In phosphor-hwmon, it is "/xyz/openbmc_project/sensors/fan_tach/".
In dbus-sensor, it is "/xyz/openbmc_project/control/fanpwm/"

This commit supports making this path configurable via "target_path".
By default, it is "/xyz/openbmc_project/sensors/fan_tach/".

Correct precondition generation

Currently, preconditions must include the set speed event as a

is removed. Related to this, actions without parameters are supported
and was corrected to allow this.

Create empty action groups

This introduces the framework for set speed events to have the groups
within an event assign directly on the event action. When a group is
defined directly to an action, it will be used in place of the group(s)
on the event. This allows a single event, driven by trigger(s), to call
multiple actions on different groups with differing parameters to those
actions.

Separate handlers for signals and method calls

Signals and method calls have different parameter structures. When the
associated event trigger is chosen, what's generated to retrieve the
dbus data is specific to that trigger event. For signals, the data is
read from the given signal message. A method call is method specific and
is called to be done against all of the members within the event group.

Convert event group to a vector of tuples

In preparation for storing each event group member's property state used
within the event's actions, the group type should be converted to a
vector of tuples. This vector will allow, if user defines, easier use of
different interfaces and properties on the same path to be used within
the same event group.

Tested:
Generated code for groups reflects vector instead of map
Actions against groups remain unchanged

Call event triggers on initialization

Move timers to be an event trigger function that is called upon event
initialization. Previously, event timers were created and started
directly within the initialization of the event, this moves the creation
and starting of a defined event timer to within a selectable event
trigger function.

With the creation of event triggers, an event can be defined with a list
of supported triggers used to execute the actions, if defined, of the
event. In the case no actions are given, the trigger is still used.

Tested:
Timer triggers are created/started correctly for an event
Events with no actions have timers created/started as defined

Generate zone property persist configs

Each zone object's hosted interfaces' properties can be configured to be
persisted or not at compile time. Those properties configured to be
persisted are set to be persisted after the initial value is set. When
this value doesnt change on a system, there's no need to persist it
since the initial value is compiled into the fan control application per
zone. Once this value is changed and therefore persisted, upon a
application restart, initially the value would be what's compiled in
until its configured again to be persisted and then restored.

Tested:
Current property always set to what's persisted between restarts
Nothing persisted when Current property doesnt change from default
