(CONT-173) - Updating deprecated facter instances

Prior to this commit, this module contained instances of Facter::Util::Resolution.execute and Facter::Util::Resolution.which, which are deprecated.
This commit aims to replace these exec helpers with their supported Facter::Core::Execution counterparts.

This commit:
- Replaced all Facter::Util::Resolution instances with Facter::Core::Execution
