Modify Trigger dbus api

'AddTrigger' method is now using array of strings for actions instead
of boolean flags. The action names are following:
- 'UpdateReport' (same as old flag)
- 'LogToLogService' (old 'LogToJournal' flag)
- 'RedfishEvent' (old 'LogToRedfish' flag)
Additionally, isDiscrete flag was removed from 'AddTrigger' call, as
this value can be extracted depending on threshold.

As a result new 'AddTrigger" signature is: "sasa{os}asv"
Example call parameters:
- TestTrigger 1 UpdateReport 0 0 "a(stsd)" 1 LowerWarning 1000
  Either 42.7'
- TestTrigger 2 UpdateReport RedfishEvent 0 0 "a(ssts)" 1 userId_1
  Warning 10 15.2'

'Trigger' properties were also modified. Instead of action bool
properties (same as mentioned above), new property was introduced
'TriggerActions' - which has same values as those used in 'AddTrigger'
method. This also affects persistence: store/load functionality was
modified accordingly.

As a side change - isDiscrete is no longer stored, as this can be easily
recreated in the runtime.

Tested:
- Trigger was successfully created using dbus.
- busctl introspect was called on test trigger and properties are
  modified and working as intended.
- persistency mechanic is working propetly.
