MODULES-4753 Add swapon command to filesystem provider

When the exec resources were removed from the lvm::logical_volume
defined type, it created a gap wherein a NEW swap lvm would not be
loaded into swap after being created.

To solve this issue, I added the swapon command and logic that will
run that command against the filesystem resource if the fs_type parameter
is set to 'swap'
