Read TPE data from the rules file.

New secadm rule section: tpe. Members of tpe:
    - enable (boolean): Enable TPE
    - all (boolean): Enable TPE for all suers
    - invert (boolean): Invert GID logic
    - gid (int): The Group ID (GID) for which TPE applies

Fully-qualified example:

secadm {
	tpe {
		enable: true,
		gid: 10,
		invert: true,
	}
}
