[Feature request]: allow configuration of fact based config options

[tuxmea]

Use Case

Prevent facter from hanging while waiting for a command to finish

Example: #46 Hung on stale NFS mounts

Describe the solution you would like

Allow configuration of options like timeout for an individual fact.

facter.conf could be the following:

options : {
 <factname> : {
    timeout: <seconds>,
  },
}

Check within the fact for the timeout setting from config file

Describe alternatives you've considered

Adding timeout to the fact without config file.
But this would affect all users.
Making it configurable sound more reasonable to me.
