Enhance apply scripts timeout management
- Values schema updates: Added support for the following timeout parameters:
- UNIT_TIMEOUT_FACTOR
- Sylva-units schema: Introduced unit_timeout_settings.UNIT_TIMEOUT_FACTOR
- common.sh : uses extractSylvaUnitsReleaseValues.py to correctly sources UNIT_TIMEOUT_FACTOR values.
- introduced get_unit_timeout_factor() function in the apply scripts.
Closes #2470
